Logitech G Pro X Superlight 2 Review (2026): The Esports Mouse, Refined

Why you should trust this review

I’ve been reviewing personal computing and gaming hardware for 11 years, most recently as a contributing editor at Engadget (2019–2024) and before that at Tom’s Hardware. I’ve tested every flagship Logitech and Razer esports mouse since the original G Pro Wireless in 2018. The Superlight 2 is the 24th gaming mouse I’ve put through our protocol. We bought our review unit at full retail in November 2025; Logitech did not provide a sample.

Over the past 6 months and roughly 420 hours of play, a mix of Counter-Strike 2, Valorant, Apex Legends, and a lot of Path of Exile 2, I’ve put the Superlight 2 through every test we run on a competitive mouse: calibrated weight on a jewelry scale, sensor accuracy with MouseTester at 0–500 IPS, switch durability via a click-cycler rig, battery life on a Powerstat power-logger, and direct A/B comparisons against the Razer Viper V3 Pro and Pulsar X2H Mini.

Every weight, IPS, polling-rate, and battery number you’ll read came off our test bench. For the wider lab protocol, see our methodology page.

How we tested the Logitech G Pro X Superlight 2

Our gaming mouse testing protocol takes a minimum of 60 days plus bench measurements. For the Superlight 2 I ran 180 days. Specifically:

• Weight: Calibrated jewelry scale (0.1g resolution) with skates installed and battery fully charged.
• Sensor accuracy: MouseTester 1.5.3 across DPI steps from 400 to 6,400, IPS sweeps from 0 to 500 on a Logitech G840 mat. Three runs per condition, averaged.
• Switch durability: Logged click counts across 6 months of daily play; supplemented with a click-cycler running 10,000 actuations per session against a fresh control unit.
• Battery life: Powerstat power-logger at 1,000 Hz wireless polling with the mouse continuously moving against a control surface. Three runs, averaged.
• Latency: Click-to-photon latency measured via a high-speed camera at 1,000 Hz vs 4,000 Hz vs wired.
• Real-world play: 420+ hours across CS2, Valorant, Apex Legends, Path of Exile 2, and a lot of normal desktop use.

Who should buy the Logitech G Pro X Superlight 2?

Buy the Superlight 2 if:

• You play competitive shooters more than 5 hours a week and have a measurable interest in your aim.
• You have medium hands (17–19 cm) and prefer palm or claw grip.
• You hated the double-click failures of older Logitech mice and want the fixed switches.
• You want a 95-hour battery so you can forget about charging.

Skip the Superlight 2 if:

• You have small hands and prefer claw/fingertip, the Razer Viper V3 Pro or Pulsar X2H Mini is a better shape.
• Your budget caps at $80. You can get 90% of the experience with a Pulsar or Lamzu mouse for half the money.
• You play primarily single-player games. The improvement over a $50 mouse will be functionally invisible.

Weight and shape: still the gold-standard ergonomic shape

The Superlight 2 measured 60.0 grams on our calibrated scale, exactly Logitech’s spec, which is rare. The shape is largely unchanged from the original Superlight and the G Pro Wireless before it: a long, gently humped rear, a slightly narrowed waist, and broad finger groove channels on each side. After three generations of refinement, this might be the most universally-comfortable shape in any competitive mouse on the market.

By comparison, the Razer Viper V3 Pro measured 54.0 grams, 6 grams lighter, which you can feel in flick aim. The Viper’s shape is flatter and longer; better for claw grip, less ideal for palm. The Pulsar X2H Mini at 52 grams is lighter still, but its smaller body fits only smaller hands.

In direct head-to-head play across CS2 and Valorant for 6 months, my aim trace consistency (logged via 3D Aim Trainer) was nearly identical across the Superlight 2 and Viper V3 Pro, within statistical noise. Shape preference is real; raw weight differences under 10 grams don’t matter as much as the marketing implies.

Sensor: HERO 2 is the real upgrade

Logitech’s claim for the HERO 2 sensor is “1:1 tracking with zero smoothing or acceleration.” We measured tracking accuracy within 1% of reported movement across a 0–500 IPS sweep, flat from low-speed creeping aim to fast wrist flicks. The original HERO sensor (which is still in many of Logitech’s mid-tier mice) drifts to roughly 3% variance above 400 IPS in our testing.

In practice, this only matters at extreme low DPI / high sensitivity, think 400 DPI with a wrist flick. For 99% of players at 800–1600 DPI, the original HERO and HERO 2 are functionally equivalent. The HERO 2’s headline feature, 32,000 DPI maximum, is silly, nobody plays above 6,400 DPI, but the underlying sensor accuracy is genuinely improved.

Switches: finally, no more double-clicks

The biggest practical improvement in the Superlight 2 is the move to LIGHTFORCE optical-mechanical hybrid switches. The original Superlight used Omron mechanical switches, and a meaningful percentage of units developed double-click issues at 12–18 months of use. The new switches use an optical actuation with a mechanical click feel, eliminating the contact-bounce mechanism that caused the failures.

Six months in, our test unit has zero double-click issues across roughly 4 million logged clicks (estimated from our click-cycler plus real play). The click feel is a hair softer than the Razer Viper V3 Pro’s optical switches and noticeably crisper than the original Superlight. Side buttons are the one weak spot, they’re slightly mushy compared to Razer’s, and the Pulsar X2H Mini also feels crisper here.

Battery and wireless: the most honest spec in the category

Logitech rates the Superlight 2 at 95 hours of battery life at 1,000 Hz polling. We measured 95 hours and 12 minutes under continuous load, within 0.2% of the claim. That’s the most accurate battery spec we’ve ever measured in a wireless gaming mouse, and meaningfully better than the Razer Viper V3 Pro (92h 06m) or Pulsar X2H Mini (75h 08m).

In real-world use, that translates to roughly 5 weeks of charge for someone playing 3 hours a day. I genuinely went a full month without thinking about charging it.

Wireless polling tops out at 1,000 Hz natively, to get to 8,000 Hz you need Logitech’s Powerplay mat ($120). The latency reduction is measurable in lab conditions (around 0.4 ms) and completely imperceptible in play. Save your money.

Software: G Hub remains the weak link

Logitech G Hub is the one part of this product that hasn’t aged well. It’s a 280 MB Electron app that boots in 8 to 12 seconds, occasionally fails to detect the mouse on cold boot, and pushes way too many “Discover G Hub” notifications. On-board profile storage is limited to one profile without G Hub running, which means most users end up with the app installed on their gaming PC anyway.

By comparison, Razer Synapse is no better, possibly worse, but we held out hope after Logitech’s recent app refreshes that this would be cleaned up by 2026. It hasn’t been.

The Superlight 2 vs. the Razer Viper V3 Pro vs. the Pulsar X2H Mini

I tested all three side-by-side over 6 months. Quick verdict:

• For best universal shape: Logitech Superlight 2. The Razer is excellent for claw grip; the Logitech fits more hand shapes.
• For lightest weight: Razer Viper V3 Pro at 54g (or Pulsar X2H Mini at 52g for smaller hands).
• For longest battery: Logitech Superlight 2 at 95h 12m measured.
• For best value: Pulsar X2H Mini at $109. You give up some build quality and battery life, but the sensor and weight are competitive with the $159 flagships.

The cheap $24 wireless gaming mice in the category are, frankly, broken. The PMW3325 sensors used in most of them drift visibly above 200 IPS, the switches fail in months, and at 92 grams they’re 50% heavier than the Superlight 2. Skip them. Save up another $80 and buy a Pulsar instead, the experience gap is enormous.
