Technical benefits: what it actually gives you

0.2 ms actuation with no debounce

Gen-3 optical switches close the circuit with light, not metal. With no mechanical bounce there's no artificial debounce delay to add (typically 4 to 8 ms on mechanical switches) and no double-clicking as the switch wears. Razer puts actuation at 0.2 ms: one of the few latency figures a manufacturer publishes as a comparable number.

Real 8000 Hz, with the dongle included

Plenty of mice advertise 8 kHz and then sell the receiver that enables it separately. Here the HyperPolling Wireless Dongle is in the box, so the 0.125 ms interval is available on day one. The trade-off is that battery life at 8 kHz drops well below the 95 h quoted at 1000 Hz.

54 g with a closed shell

It's among the lightest mice with a solid, unperforated shell. The six grams it saves over a Superlight 2 show up most when stopping: less inertia means the mouse halts where you halt, which is exactly what the final micro-correction of a flick needs.

How it performs by game type

Tactical shooters

Valorant · CS2
10/10

The favourite of half the Valorant scene. The flat, symmetrical shape suits claw and fingertip perfectly, 54 g allows very fast flicks, and the included 8 kHz polling cuts latency variance at the moment that matters most: the frame a head appears.

Mechanical speed and precision

Rocket League
8/10

It works well, but the flat, light shape favours flicking over the smooth sustained tracking Rocket League asks for. If you play on mouse with a palm grip, a taller shape will give you more support on long camera swings.

High click-rate PvP

Minecraft
9/10

Gen-3 optical switches with 0.2 ms actuation and no debounce are among the best options for high-CPS PvP: the click registers the instant you make it, the reset is immediate, and there are 90 million clicks of rated life to survive jitter clicking.

Mixed competitive play

Roblox
9/10

Light, symmetrical in shape (though the side buttons are only on the left) and very comfortable for small and medium hands, which is the typical Roblox player. At 1000 Hz its 95 hours of battery will last you weeks between charges.

Pros, cons and who it's for

Strengths

  • 54 g: among the lightest with a closed shell
  • 8000 Hz dongle included in the box
  • Gen-3 optical switches with 0.2 ms actuation and no debounce
  • Two-year warranty, one more than its direct rivals
  • Tracks on glass as well

Weaknesses

  • At 8000 Hz real battery life falls well short of the 95 h headline
  • Flat shape: it can feel low if you use a pure palm grip
  • No RGB and no wireless charging via a pad
  • Synapse is heavy for how little there is to configure

Ideal for: Anyone on claw or fingertip grip who wants the lowest possible latency without paying extra for an 8 kHz dongle.

Review summary

The reviews are dominated by shooter players coming from a 60-70 g mouse who describe the change as a clear jump in flick speed. Mentions of the button feel and claw-grip comfort recur. The usual complaint is the price, and a few buyers note the flat shape doesn't suit their palm grip.
