BUYING GUIDE

Mouse Buying Guide India 2026: DPI, Sensors and Grip

Q: Is a higher DPI mouse better?

No. Higher DPI moves the cursor faster, not more precisely. Precision is capped by your screen’s pixel grid, so past a point extra DPI adds no information — it just crosses more pixels per inch of hand movement. RTINGS states that a higher CPI range alone "does not necessarily mean a sensor is more accurate", and most people find 800–3200 DPI most comfortable. This is why competitive players go the other way: across 623 tracked Valorant pros, essentially none play above 1,600 DPI and around 90% use 400 or 800. Buy for the shape, weight and build — not the DPI number on the box.

Q: Do I need an 8000Hz polling-rate mouse?

Almost certainly not. Polling rate is how often the mouse reports to the PC. Going from 1000Hz to 8000Hz cuts the report delay from 1ms to 0.125ms — a total saving of 0.875ms, which is less than one-seventh of a single frame on a 144Hz monitor. NVIDIA measures 1000Hz at about 1ms of latency, and the jump to 1000Hz is the one that matters. Above that the gains are very hard to notice unless you run a 360Hz-plus display, and 8000Hz costs extra CPU load and drains a wireless battery faster. Set 1000Hz and forget it.

Q: Optical or mechanical switches — which lasts longer?

Optical switches last longer and resist the double-click fault. A mechanical switch closes two metal contacts that physically bounce; as they wear and oxidise, one press can register as two clicks, and firmware "debounce" only masks it. Optical switches trigger with an infrared beam and no metal contact, so that failure mode is physically absent. Razer rates its optical switches at 70–100 million clicks by generation; good mechanical switches like the Kailh GM 8.0 are rated around 80 million, while the cheapest mice use 5–10 million-rated switches that fail first. If a mouse is developing double-clicks, its switches are worn.

Q: How light should a gaming mouse be?

Lighter helps for fast aiming, but there is a floor. Flagship wireless gaming mice now weigh around 54–60g (the Razer Viper V3 Pro is 54g, the Logitech G Pro X Superlight 2 is 60g). Lower mass needs less force to start and stop, which aids flicks and reduces fatigue — mostly for fingertip and claw grips. Many players find the 50–60g band the sweet spot; below 50g some aim worse because the mouse becomes twitchy. For office work and palm grip, weight barely matters — a larger, stable body is often more comfortable.

Q: Is a wireless mouse good enough for gaming?

Yes — if it uses a 2.4GHz USB receiver, not Bluetooth. RTINGS finds that many gaming mice with proprietary receivers now match or beat wired mice on latency, with both rated "good" under 10ms. Bluetooth is the exception: it usually polls at about 125Hz and adds noticeable lag, so it is fine for office and travel but not for competitive play. So buy a 2.4GHz dongle mouse for gaming, use Bluetooth for productivity and multiple devices, and pick wired only to save money or avoid ever charging.

Q: Does a vertical or ergonomic mouse prevent RSI?

It reduces strain, but "prevents RSI" overstates it. Peer-reviewed EMG studies show a vertical mouse lowers forearm pronation — one measured 28° versus 42° for a standard mouse — and reduces wrist-extensor muscle activity. A 25–30° slant is linked to less pronation and lower muscle load. However, a 2018 systematic review notes these benefits are "not yet supported by high-quality clinical trials", so the honest claim is reduced wrist pronation and forearm strain, not a cure for carpal tunnel. If you have wrist pain, a vertical mouse or a trackball is worth trying, ideally with ergonomic setup advice.

Q: What DPI should I use for gaming versus office work?

For competitive FPS aiming, 400–800 DPI paired with a large mousepad gives the finest control and least overshoot — which is exactly what the pros use. For office work, MOBA and RTS games, 800–1600 DPI moves the cursor quickly across spreadsheets and maps without feeling twitchy. On a 4K or multi-monitor setup, 1600 DPI and up helps because there are more pixels to cross. Stick to native steps — 400, 800, 1600, 3200 — since in-between values force the sensor to interpolate and can add jitter.

Q: Does the sensor still matter when buying a mouse in 2026?

For about 99% of buyers, no — it is effectively a solved problem. RTINGS puts it plainly: "most modern mouse sensors, even in budget models, have reasonably low latency, and most people won’t notice any difference." Even budget mice now track flawlessly across normal speeds. The sensor only becomes decisive at the extreme competitive tier, or in one edge case: standard optical sensors still fail on glass and glossy surfaces, so if you must use bare glass you need a glass-capable sensor or a proper mousepad. Otherwise, judge shape, weight, switches, wireless quality and price.

Q: Which mouse brands are reliable to buy in India?

Logitech is the safe pick at every tier — the deepest range and the smoothest warranty and replacement experience, especially when bought Amazon-fulfilled. Razer is strong for enthusiast and flagship mice, but its Indian MRPs are inflated, so buy on discount and track price history. Cosmic Byte is the standout value brand, putting real PixArt sensors, paracord cables and PTFE feet on sub-₹1,000 mice. HP, Dell, Lenovo and Zebronics cover reliable basic office use. SteelSeries, Corsair and Glorious appear but with narrower or grey-import availability, so confirm the warranty path before buying.

Almost every number on a mouse box is either marketing or a spec you are reading wrong. 30,000 DPI does not make you accurate, 8000Hz polling saves you under a millisecond, and the sensor stopped mattering years ago. This guide works from the specs that decide how a mouse actually feels — shape, weight, switches, grip and wireless quality — so you buy the mouse, not the spec sheet.

Updated Aug 2026 Every claim sourced Research-based, not hands-on

Start here: the five decisions that actually matter

A mouse spec sheet has dozens of lines, but the buying decision collapses to five choices. Get these right and the rest is detail. We take them in order, because each one narrows the next.

1

What will you mostly do with it?

Office, FPS gaming, MMO, creative work or travel. This sets everything else. The six types, below.
2

What is your hand size and grip?

The single biggest driver of comfort, and the spec nobody prints. Measure your hand first. Grip and hand size.
3

Wired, 2.4GHz dongle, or Bluetooth?

A 2.4GHz dongle now matches wired for gaming; Bluetooth is for office and travel. The latency numbers.
4

How much does weight matter to you?

Critical for fast aim, irrelevant for office palm-rest comfort. Weight and shape.
5

What is your real budget band?

Indian MRPs are inflated, so shop by band and track price history. India price bands.

THE MOST COMMON MISTAKE

Shopping by the headline numbers — DPI, polling rate, sensor model — instead of the things you actually feel. Two mice with identical spec sheets can feel completely different in the hand. The rest of this guide is a translation layer between the box and the reality.

The six types of mouse

Place yourself in one of these first. It rules out most of the market before you look at a single spec.

EVERYDAY

Office / productivity

Comfort and quiet over speed. Often heavier, wireless, with multi-device switching and long battery. Weight is irrelevant here.

SPEED

Gaming (FPS)

Lightweight and low-profile, with a 2.4GHz dongle or a cable and a flawless sensor. This is where weight and shape dominate.

COMFORT

Ergonomic / vertical

A slanted or vertical body that cuts forearm pronation. For comfort and wrist strain, not for speed.

STATIONARY

Trackball

The ball moves, not the mouse, so your hand and arm stay still. Good for tight desks and reducing arm travel.

PORTABLE

Travel / laptop

Small, low-profile, Bluetooth so there is no dongle to lose, and a long battery. Latency does not matter here.

BUTTONS

MMO / high-button

A 12-button thumb panel for mapping abilities or macros. Button density is the point; agility is secondary.

The DPI myth: higher is faster, not better

This is the one thing to un-learn before buying. DPI (or CPI, counts per inch) is how far the cursor travels per inch of hand movement. Higher DPI moves the cursor faster. It does not make you more precise. Precision is capped by your screen’s pixel grid, so beyond a point extra DPI adds no information at all.

RTINGS confirms a higher CPI range alone "does not necessarily mean a sensor is more accurate", and that most people find 800 to 3200 DPI most comfortable. The proof is in how professionals set up: across 623 tracked Valorant players, essentially none play above 1,600 DPI, and around 90% use just 400 or 800.

STICK TO NATIVE STEPS

Sensors have native DPI steps at multiples of 50 or 100 — 400, 800, 1600, 3200. Pick an in-between value like 1030 and the firmware has to interpolate, which does not add real resolution and can introduce jitter. Choose a native step and adjust in-game sensitivity instead.

What DPI to actually use

Recommended DPI range by use case
Use case	DPI range	Why
Competitive FPS	400–800	Finest control, least overshoot, with a large pad
Office / MOBA / RTS	800–1600	Quick across spreadsheets and maps, still controllable
4K / multi-monitor	1600+	More pixels to cross per inch of desk
Creative / CAD	Adjustable	Low for fine node work, higher for panning canvases

Scroll the table sideways to see all columns.

A useful shortcut the pros use is eDPI — your DPI multiplied by in-game sensitivity. It is the true crosshair speed, and it is why 400 DPI at 1.0 sensitivity feels identical to 1600 DPI at 0.25. Set a low native DPI, then tune sensitivity to taste.

Sensors: a solved problem for almost everyone

The sensor is the part buyers worry about most and need to worry about least. RTINGS is blunt: "most modern mouse sensors, even in budget models, have reasonably low latency, and most people won’t notice any difference in movement delay between mice." For roughly 99% of users, the sensor is no longer what separates a good mouse from a bad one.

Optical vs "laser" — and why laser lost

An optical mouse lights the surface with an LED and photographs it thousands of times a second, computing motion from the frames. A "laser" mouse uses an infrared laser diode instead. Every current flagship gaming sensor uses an LED — often an infrared LED at 850nm, which is why "IR" on a spec sheet does not mean "laser." Laser keeps one genuine edge: it can track on glass and glossy surfaces, where standard optical sensors fail.

THE ONE SURFACE THAT STILL BREAKS SENSORS

Standard optical mice do not work properly on glass, transparent or specular surfaces, and multicoloured pads can confuse them. If your desk is bare glass, you need a glass-capable sensor or, more simply, a proper mousepad. This is the one place the optical-versus-laser choice still bites.

What the flagship sensors actually spec

Datasheet specifications for common gaming sensors
Sensor	Max DPI	Max speed (IPS)	Max accel
PixArt PMW3360	12,000	250	50 G
PixArt PMW3389	16,000	400	50 G
PixArt PAW3395	26,000	650	50 G
Logitech HERO 2	44,000	888	88 G
Razer Focus Pro 30K	30,000	750	70 G

Scroll the table sideways to see all columns.

Read that table and then forget it. Useful DPI sits at 800 to 3200, which every sensor here clears many times over. Human hand motion never approaches even the slowest 250 IPS or 50 G rating. These headline numbers are a spec race, not a buying signal.

The traits that do still matter are subtle: no smoothing, acceleration or angle-snapping (so on-screen motion is a 1:1 map of your hand), and a low, adjustable lift-off distance if you lift and reposition often. The good news is that these are now common even on mid-range mice.

Polling rate: set 1000Hz and stop worrying

Polling rate is how many times per second the mouse reports to the PC. The report delay is simply 1000 divided by the rate: 125Hz is 8ms, 500Hz is 2ms, 1000Hz is 1ms, and 8000Hz is 0.125ms. The jump most people can feel is the one up to 1000Hz. Everything above it is chasing fractions of a millisecond.

Polling rate and the maximum report delay it produces
Polling rate	Max report delay	Verdict
125 Hz	8 ms	Too slow for gaming
500 Hz	2 ms	Fine for most
1000 Hz	1 ms	The right default
4000 Hz	0.25 ms	Competitive only
8000 Hz	0.125 ms	360Hz+ displays only

Scroll the table sideways to see all columns.

THE 8000Hz REALITY CHECK

The entire gain from 1000Hz to 8000Hz is 0.875ms. That is less than one-seventh of a single frame on a 144Hz monitor, where one frame lasts 6.9ms. NVIDIA measures 1000Hz at about 1ms of latency. Unless you run a 360Hz-plus display and play competitively, 8000Hz mostly buys you extra CPU load and faster battery drain.

One more thing polling does not do: it only shrinks the mouse’s own latency. Your PC’s render time and your monitor’s response usually dominate total system lag by a wide margin. A faster mouse cannot fix a slow frame rate.

Switches: where cheap mice die first

The click switch is the part most likely to fail, usually as the dreaded double-click. There are three kinds, and the difference is real.

METAL CONTACT

Mechanical

Two metal contacts close on each press. Rated by lifespan bin, from 20 million to 100 million clicks. Kailh GM 8.0 is rated around 80 million; the cheapest mice use 5–10 million switches.

INFRARED BEAM

Optical

An infrared beam registers the click with no metal contact, so there is no bounce to wear out. Razer rates its optical switches at 70–100 million clicks by generation.

BEST OF BOTH

Hybrid

Logitech LIGHTFORCE keeps a mechanical click feel but actuates optically, so debounce delay is not needed and the switch lasts longer.

WHY MICE START DOUBLE-CLICKING

A mechanical switch’s metal contacts physically bounce on each press. As they wear and oxidise, the contact resistance rises and one press can register as two clicks. Firmware "debounce" only masks the fault by ignoring signals for a moment — it cannot cure it, and turning it up adds click latency. Optical switches have no metal contact, so this failure mode is physically absent. That is the real reason they were invented.

Weight and shape: the ultralight era

Gaming mice have shed a remarkable amount of weight. Flagship wireless mice now sit around 54 to 60 grams — the Razer Viper V3 Pro is 54g, the Logitech G Pro X Superlight 2 is 60g. Lower mass takes less force to start and stop, which helps fast flicks and cuts fatigue, mostly for fingertip and claw grips.

But lighter is not endlessly better. Many players find 50 to 60 grams the sweet spot; below 50g some aim worse because the mouse becomes twitchy on fine adjustments. And for office work with a palm grip, weight barely registers — a larger, heavier, stable body is often the more comfortable choice.

YOU NO LONGER NEED HONEYCOMB

Around 2019 to 2021, the only way to get a sub-60g mouse was a shell full of holes, with real downsides: dust ingress, less rigidity and an odd texture. Modern magnesium and thin-wall solid shells now hit the same weights with no holes at all, so a honeycomb shell is no longer a reason to buy — or to compromise.

Grip and hand size: the fit that decides comfort

This is the spec nobody prints and the one that matters most. How you hold a mouse, and how big your hand is, decide which shapes will ever feel right. Work it out before you shop.

MOST CONTACT

Palm grip

Your whole palm rests on the back. Relaxed and stable, best on tall, longer mice. Great for slow, precise gliding; weaker for fast flicks.

BALANCED

Claw grip

Fingers arched, less palm contact. Better for fast movement and precision than palm, and suits medium mice with a lower back.

LEAST CONTACT

Fingertip grip

Only your fingertips touch. Superb for quick flick shots on short, low, light mice; weaker for slow precise work.

Match the mouse to your hand

RTINGS measures hand length from the tip of the middle finger to the wrist. Find your bracket, then use it with the grip guidance above: smaller mice suit fingertip grip at any hand size, while larger mice suit claw or palm.

Hand-size brackets by hand length, measured middle fingertip to wrist
Hand size	Length (cm)	Length (in)	Tends to suit
Small	14.0–17.5	5.5–6.9	Small mice, fingertip/claw
Medium	17.0–19.5	6.7–7.7	Most mice, any grip
Large	19.0–20.5	7.5–8.1	Larger mice, palm/claw
Extra large	20.0–24.0	7.9–9.5	Large mice, palm; fingertip possible

Scroll the table sideways to see all columns.

If you can, hold a mouse before buying, or check its length and width against one you already like. A shape that fights your grip will annoy you long after the DPI number stops mattering.

Wired vs wireless: the argument is over

A good 2.4GHz wireless mouse now matches a wired one for gaming. RTINGS finds that many gaming mice with proprietary USB receivers "match or even surpass wired models" on latency, with both rated good under 10ms. The catch is Bluetooth: it usually polls at around 125Hz and adds noticeable lag, so it is for office and travel, not competitive play.

Latency and best use by connection type
Connection	Click latency	Best for
Wired	< 10 ms	Lowest cost, never charge, most consistent
2.4GHz dongle	< 10 ms	Gaming, no cable drag
Bluetooth	< 20 ms	Office, travel, multi-device

Scroll the table sideways to see all columns.

Battery and multi-device

Wireless battery life varies by purpose, and the numbers are large. Gaming mice run roughly 40 to 95 hours per charge; the Logitech G Pro X Superlight 2 is rated up to 95 hours. Office mice last far longer — the MX Master 3S quotes 70 days, and the M720 Triathlon up to 24 months on a single AA. USB-C charging is now standard, and a one-minute top-up on the MX Master 3S gives about 3 hours of use.

If you switch between a desktop, laptop and tablet, look for multi-device features: Logitech Easy-Switch hops between three paired devices, and Flow moves the cursor across computers with copy and paste. These matter far more for real productivity than any gaming spec.

Ergonomics and health: the honest version

Vertical and slanted mice are marketed hard for wrist health, and the evidence is real but narrower than the ads suggest. Peer-reviewed EMG studies show a vertical mouse lowers forearm pronation — one measured 28° versus 42° for a standard mouse — and reduces wrist-extensor muscle activity. A 25 to 30 degree slant is linked to less pronation and lower muscle load.

"REDUCES STRAIN", NOT "PREVENTS RSI"

A 2018 systematic review found these benefits are "not yet supported by high-quality clinical trials." So the honest claim is reduced wrist pronation and forearm strain — not a cure for carpal tunnel or RSI. If you have wrist pain, a vertical mouse or a trackball is worth trying, ideally alongside proper desk setup, but treat it as comfort, not medicine.

Two more shape decisions matter for specific buyers. Left-handers need a truly ambidextrous mouse — symmetric shape with side buttons on both sides — or a dedicated left-handed model, because most ergonomic mice are right-slanted and unusable in the left hand. Trackball users keep the hand and arm still, which suits tight desks and reduces arm travel.

Feet, cable, software and build

The small details separate a mouse that feels premium from one that feels cheap, long after the spec sheet is forgotten.

Feet. PTFE (Teflon) is the standard glide material. Pure "virgin-grade" PTFE glides smoother than cheaper dyed feet.
Cable. On wired mice, a flexible braided "paracord" cable reduces drag and mimics a wireless feel; stiff rubber cables tug back.
Build. Squeeze the shell for flex, creak or rattle. Matte and textured coatings hold grip when your hand sweats; glossy shells get slippery.
Onboard memory. It stores DPI, polling and button maps on the mouse itself, so your settings follow you to any PC without vendor software running.
RGB. Cosmetic, and on a wireless mouse it draws real battery. High polling drains even more. Neither changes how the mouse performs.

Best mouse by use case

Pull the threads together. Here is what actually matters for each kind of buyer, and where to go next for specific picks with current prices.

FPS gaming

Lightweight (under 60–65g), a 2.4GHz dongle at 1000Hz, a flawless sensor and a low-profile shape. Never Bluetooth for play.

MOBA / general gaming

A balanced medium shape with a few extra buttons and a 2.4GHz connection. Comfort over raw lightness.

MMO

A 12-button thumb panel for abilities and macros. Palm or claw grip; button density is the priority.

Office / productivity

Bluetooth is fine here. Prioritise multi-device switching, quiet clicks, long battery and a comfortable palm shape.

Creative / CAD

A high-resolution scroll wheel, a thumb wheel and many mappable buttons. Precision and buttons beat lightness.

Travel / left-handed / RSI

Small Bluetooth for travel; a truly ambidextrous mouse for left-handers; a vertical mouse or trackball for wrist strain.

India price bands: what each budget really buys

Indian mouse prices swing hard during Great Indian Festival and Big Billion Days, and flagship MRPs are often inflated so the "discount" is really the normal price. Shop by band, track price history, and treat every figure below as approximate — verify at purchase.

What each price band buys in India, with representative models
Band	What it buys	Representative models
Under ₹500	Basic wired optical office, 1000–1600 DPI	Logitech B100/M90, Zebronics, HP Wired 100
₹500–1,500	Wireless office or entry gaming	Cosmic Byte Firestorm, Logitech G102, Ant Esports GM300
₹1,500–3,000	Solid gaming, real wireless, better sensors	Logitech G304 Lightspeed, Razer DeathAdder Essential
₹3,000–6,000	Quality wireless gaming, good switches	Logitech G502 Hero, Razer Basilisk V3, SteelSeries Aerox 3
₹6,000+	Flagship wireless esports	Logitech G Pro X Superlight 2, Razer DeathAdder V3 Pro

Scroll the table sideways to see all columns.

THE VALUE PICKS

Cosmic Byte Firestorm is the best price-performance mouse in the market — a genuine PixArt sensor, paracord cable and PTFE feet for around ₹999. Logitech G304 is the cheapest true-wireless gaming mouse worth owning. At the top, Razer DeathAdder V3 Pro often undercuts the Logitech flagship while matching its weight and sensor — just confirm the seller is Amazon-fulfilled and the discount is genuine.

On brands: Logitech is the safe choice at every tier thanks to the widest range and the smoothest Indian warranty and replacement. Cosmic Byte, Ant Esports and Redgear own the budget end. HP, Dell and Zebronics cover reliable basic office. Note that any wireless mouse sold legitimately in India needs WPC/ETA radio approval, which officially imported units carry along with a valid warranty.

The spec checklist

Before you buy, run down this list. If a mouse clears it for your use case, the headline numbers do not matter.

Grip and hand size fit. The shape suits your grip and hand length — the single biggest comfort factor.
Weight suits the job. Light (50–60g) for FPS; weight is irrelevant for office palm use.
Right connection. 2.4GHz dongle for gaming, Bluetooth for office and travel, wired to save money.
Switch quality. Optical or a high-rated mechanical switch, not a nameless 5–10 million-click part.
1000Hz polling. The right default; ignore 8000Hz unless you run a 360Hz-plus display.
A native DPI you will actually use. 400 to 3200 covers almost everyone; the max DPI number is noise.
Battery and charging (if wireless) match your habits, with USB-C and multi-device if you need them.
Warranty and seller. Buy Amazon-fulfilled or from an official importer so the India warranty is valid.

Frequently asked questions

Is a higher DPI mouse better?

No. Higher DPI moves the cursor faster, not more precisely. Precision is capped by your screen’s pixel grid, so past a point extra DPI adds no information — it just crosses more pixels per inch of hand movement. RTINGS states that a higher CPI range alone "does not necessarily mean a sensor is more accurate", and most people find 800–3200 DPI most comfortable. This is why competitive players go the other way: across 623 tracked Valorant pros, essentially none play above 1,600 DPI and around 90% use 400 or 800. Buy for the shape, weight and build — not the DPI number on the box.

Do I need an 8000Hz polling-rate mouse?

Almost certainly not. Polling rate is how often the mouse reports to the PC. Going from 1000Hz to 8000Hz cuts the report delay from 1ms to 0.125ms — a total saving of 0.875ms, which is less than one-seventh of a single frame on a 144Hz monitor. NVIDIA measures 1000Hz at about 1ms of latency, and the jump to 1000Hz is the one that matters. Above that the gains are very hard to notice unless you run a 360Hz-plus display, and 8000Hz costs extra CPU load and drains a wireless battery faster. Set 1000Hz and forget it.

Optical or mechanical switches — which lasts longer?

Optical switches last longer and resist the double-click fault. A mechanical switch closes two metal contacts that physically bounce; as they wear and oxidise, one press can register as two clicks, and firmware "debounce" only masks it. Optical switches trigger with an infrared beam and no metal contact, so that failure mode is physically absent. Razer rates its optical switches at 70–100 million clicks by generation; good mechanical switches like the Kailh GM 8.0 are rated around 80 million, while the cheapest mice use 5–10 million-rated switches that fail first.

So buy a 2.4GHz dongle mouse for gaming, use Bluetooth for productivity and multiple devices, and pick wired only to save money or avoid ever charging.

Does a vertical or ergonomic mouse prevent RSI?

It reduces strain, but "prevents RSI" overstates it. Peer-reviewed EMG studies show a vertical mouse lowers forearm pronation — one measured 28° versus 42° for a standard mouse — and reduces wrist-extensor muscle activity. A 25–30° slant is linked to less pronation and lower muscle load.

What DPI should I use for gaming versus office work?

For competitive FPS aiming, 400–800 DPI paired with a large mousepad gives the finest control and least overshoot — which is exactly what the pros use. For office work, MOBA and RTS games, 800–1600 DPI moves the cursor quickly across spreadsheets and maps without feeling twitchy. On a 4K or multi-monitor setup, 1600 DPI and up helps because there are more pixels to cross. Stick to native steps — 400, 800, 1600, 3200 — since in-between values force the sensor to interpolate and can add jitter.

Does the sensor still matter when buying a mouse in 2026?

For about 99% of buyers, no — it is effectively a solved problem. RTINGS puts it plainly: "most modern mouse sensors, even in budget models, have reasonably low latency, and most people won’t notice any difference." Even budget mice now track flawlessly across normal speeds. The sensor only becomes decisive at the extreme competitive tier, or in one edge case: standard optical sensors still fail on glass and glossy surfaces, so if you must use bare glass you need a glass-capable sensor or a proper mousepad. Otherwise, judge shape, weight, switches, wireless quality and price.

Which mouse brands are reliable to buy in India?

Logitech is the safe pick at every tier — the deepest range and the smoothest warranty and replacement experience, especially when bought Amazon-fulfilled. Razer is strong for enthusiast and flagship mice, but its Indian MRPs are inflated, so buy on discount and track price history. Cosmic Byte is the standout value brand, putting real PixArt sensors, paracord cables and PTFE feet on sub-₹1,000 mice. HP, Dell, Lenovo and Zebronics cover reliable basic office use.
