Our mouse picks

The Razer Viper V4 Pro is the best gaming mouse compareelectronic tracks in the UK in May 2026 at £155. The Viper V4 Pro is a symmetric wireless mouse that weighs 49 g, ships the Razer Focus Pro 30K sensor scaling to 50,000 DPI, polls at 8 kHz, and lasts 180 hours per charge. The Logitech G Pro X Superlight 2 at £104 is the lightest credible pick at 35 g. The Razer Basilisk V3 Pro 35K at £169 is the right ergonomic and MMO pick with 13 programmable buttons.

Grip style decides the mouse, not the brand

The single biggest mistake when buying a gaming mouse is picking by spec sheet instead of grip. Every shortlist on this page is competitive, the differences are how the shell sits in your hand. Three grip styles cover almost every player:

• Fingertip grip: The mouse sits under your fingertips with the palm not touching the shell. Best served by symmetric ultralight mice 50 g and under. The Viper V4 Pro and Superlight 2 both fit here. Aim is controlled by finger movement, micro-adjustments are quick, and your wrist barely moves.
• Claw grip: Fingertips arched, palm touching the back of the shell only. Works well with symmetric mice between 50 and 70 g. Most CS2 players land somewhere in this zone. The Viper V4 Pro is the popular claw-grip flagship.
• Palm grip: Whole hand on the shell, palm flush. Demands an ergonomic right-hand shape and a thumb rest. The Basilisk V3 Pro is built for this. Heavier mice in palm grip are fine because the wrist is doing larger movements, not finger flicks.

Trace the outline of your hand against your monitor. If your fingers naturally arch, you are a claw or fingertip player. If your palm flattens, you are a palm player. Buy the shell that matches.

The three numbers that actually matter

• Weight in grams: Below 60 g is featherweight territory, 60 to 80 g is the competitive sweet spot, above 100 g is palm-grip ergonomic. The jump from 90 g to 50 g feels enormous in the first hour. The jump from 50 g to 35 g is real but smaller. Most pros land in the 49 to 70 g band.
• Polling rate in Hz: 1,000 Hz polling means the mouse reports its position 1,000 times per second. 4 kHz and 8 kHz polling halve and quarter the input lag. The catch: 8 kHz needs a CPU and game engine that keeps up. Below an RTX 5060 / Ryzen 5 7600, 4 kHz is the sensible setting. The Viper V4 Pro and Basilisk V3 Pro both poll at 8 kHz. The Superlight 2 caps at 2 kHz on the standard receiver.
• Sensor DPI ceiling: 26,000 DPI was a marketing number in 2022. 30,000 to 50,000 DPI in 2026 is the same marketing number. Nobody plays at 30 K DPI. What matters is the underlying sensor lineage. Razer Focus Pro 30K, Logitech HERO 2, and Pixart PMW3950 are the three sensors competitive players trust. Anything advertised as a generic "high-precision optical sensor" without a brand name is doing creative marketing.

1. Razer Viper V4 Pro - best overall

The Razer Viper V4 Pro is the mouse pros pick when nothing on the spec sheet is allowed to slow them down. 49 g puts it in the same featherweight tier as the Superlight 2 while retaining a slightly fuller shape that suits claw grip a touch better. The Focus Pro 30K sensor is paired with Razer's HyperSpeed 2.4 GHz wireless and tops out at 8 kHz polling on the included dongle, which is genuinely a measurable improvement over 1 kHz in 360-Hz monitors and modern engines.

Battery life is the under-stated win. 180 hours per charge means a tournament weekend on one cable. The optical mouse switches feel quick rather than soft, the scroll wheel has enough tactile detent for weapon switching without accidental scrolls, and the PTFE feet glide cleanly on both hard and soft pads. You pay the flagship price; you get a mouse with no compromise the spec sheet can find.

2. Logitech G Pro X Superlight 2 - best featherweight

The Logitech G Pro X Superlight 2 is the mouse a serious majority of CS2 and Valorant pros actually compete with. The original Superlight invented the under-60-g symmetric flagship category, and the Superlight 2 drops weight to 35 g without compromising the shape that made the original work. The HERO 2 sensor tracks at 44,000 DPI and 888 IPS, the optical mouse switches are clicky and quick, and the Lightspeed wireless has a decade of refinement behind it.

The trade-off versus the Viper V4 Pro is polling. The standard Superlight 2 receiver runs at 2 kHz; the 8 kHz ceiling requires the PowerPlay mat as a paired accessory. That is a deliberate choice from Logitech, since most gaming PCs see no measurable benefit above 2 kHz on a 240 Hz monitor. If you run a 480 Hz competitive monitor and a Ryzen 7 9800X3D or stronger, you might prefer the Viper. For most setups the Superlight 2 is the more comfortable, more proven shell.

3. Razer Basilisk V3 Pro 35K - best ergonomic

The Razer Basilisk V3 Pro 35K is the mouse that wins when competitive shooters are not your only game. 13 programmable buttons cover an MMO action bar, the tilt-click scroll wheel doubles your binds, and the sculpted right-hand shape gives palm grippers a thumb rest and a pinky rest where the Viper has neither. The Focus Pro 35K sensor is a peer of the 30K on the Viper for gaming use, and the optical switches are the same generation.

The honest caveat is weight. At 112 g the Basilisk is heavier than every competitive flick-aim mouse on the market, and a competitive CS2 player would not pick this shell. That is not what it is for. World of Warcraft, Final Fantasy XIV, Destiny 2, Path of Exile, Helldivers 2: this is the mouse that gives you a button for every action your hotbar carries, with a 140-hour battery, optional wireless charging on the dock, and Bluetooth for laptop duty.

DPI is not sensitivity, eDPI is

DPI counts how many sensor reports the mouse sends per inch of physical movement. Sensitivity is a multiplier the game applies on top. The actual on-screen turn speed is eDPI: DPI multiplied by in-game sensitivity. A pro running 800 DPI at 0.5 sensitivity in Valorant has the same eDPI as another pro at 1,600 DPI and 0.25 sensitivity. The mouse ceiling does not change that calculation.

The reason a 30,000 DPI sensor still matters is fidelity at the DPI you actually use. Modern sensors track cleanly across the full range. Older sensors smeared the lower DPI settings, which is why a 2018 mouse at 800 DPI feels notchier than a 2026 mouse at 800 DPI even though both should report 800 ticks per inch. Buy the sensor generation, not the marketing number.

Wireless versus wired in 2026

The wireless-equals-lag argument died around 2020. Razer HyperSpeed, Logitech Lightspeed, and the equivalent implementations from SteelSeries and others all match a wired USB connection on every public latency measurement most communities trust. The Viper V4 Pro and Superlight 2 are both routinely measured below 1 ms end-to-end on the included dongles. Wired mice still exist for under-£50 builds where the wireless tax is not worth it, but every flagship since 2022 has been wireless-first.

What still matters: keep the USB receiver on a 1 metre extension cable on the desk in line of sight of the mouse, not plugged into the back of the PC. 2.4 GHz signal is line-of-sight friendly and degrades fast through a tower chassis. The extension is in the box of every shortlist pick here.

Mistakes to avoid when buying a gaming mouse

• Buying for the spec sheet: A 50,000 DPI ceiling does not make you a better aimer than a 26,000 DPI ceiling. Almost everyone plays between 400 and 1,600 DPI. The numbers above that are marketing.
• Ignoring the shape: A 35 g featherweight in a palm grip is uncomfortable after twenty minutes. A 112 g ergonomic in a fingertip grip is exhausting after an hour. Trace your hand, pick the shell first, then argue about polling.
• Cheap optical switch knockoffs: Optical mouse switches do not develop the double-click drift that mechanical switches eventually do. But sub-£40 wireless mice that advertise "optical switches" without naming the part number often use cheap Huano or generic switches that fail within a year. Look for Omron or named Razer / Logitech optical assemblies.
• Skipping the mousepad: The best mouse on a cheap, sticky desk mat plays worse than a £30 mouse on a properly broken-in cloth pad. Glide consistency matters more than DPI ceiling for most aim styles.

Verdict

The Razer Viper V4 Pro at £155 is the best gaming mouse compareelectronic tracks in the UK in May 2026. The Viper V4 Pro is a 49 g symmetric wireless mouse that ships the Razer Focus Pro 30K sensor with a 50,000 DPI ceiling, 8 kHz polling on the standard dongle, optical mouse switches, and a 180-hour battery. The Logitech G Pro X Superlight 2 at £104 is the right pick if you want the proven tournament shape at 35 g and do not care about 8 kHz polling outside a PowerPlay setup. The Razer Basilisk V3 Pro 35K at £169 is the right pick for MMO players, palm grippers, and anyone who wants 13 programmable buttons and a sculpted right-hand shape.
