BenQ Zowie U2 vs Lamzu Maya X

Zowie builds for one customer, the competitive shooter player, and the U2 is what that produces. It weighs 60g, which is in the same class as Logitech's Superlight, on a symmetrical shell with double-curved sides that suits a claw grip particularly well. There are five buttons and no more.

The part that changes daily use is the receiver. Zowie's enhanced wireless receiver sits on the desk and takes the mouse on pogo pins, so it charges in the place you already put it down rather than needing a cable found and plugged in. Battery life runs to around 70 hours, which means the charge is a background event.

It is driverless by design: DPI, polling rate and lift-off distance are set with buttons on the mouse and stored in it, so there is no application running and no account to make. That is either the best or the worst thing about it depending on what you want. If you need macros, per-game profiles or RGB, this mouse refuses to provide them. The 3200 DPI ceiling is deliberate and well above competitive use, but it will annoy anyone running a very high-resolution multi-monitor desktop. And the plain matte finish, with no rubber side grips, gets slippery once your hands warm up.

The Maya X is what the current top of this category looks like. It weighs 47g without holes cut in the shell, runs the PixArt PAW3950, and ships with the 8K dongle in the box rather than as a separate purchase, so 8000Hz polling works wirelessly out of the packet.

The switches are optical, rated by Lamzu beyond 70 million actuations, which structurally avoids the double-click failure that eventually kills mechanical-switch mice. The scroll encoder is a dust-proof 30-grid design, which addresses the other common long-term failure: scroll wheels that start skipping after grit works into them. The symmetrical shell accommodates palm, claw and fingertip grips, which is unusual for something this light.

The costs are the ones every 8K mouse has. Lamzu quotes up to 80 hours at 1000Hz, falling to about 20 hours at 8000Hz, so running the headline polling rate turns charging from weekly into every second or third day. 8000Hz also puts real load on the CPU, and on an older processor it can cost more frame-rate stability than the polling rate gains you. There are no side grips, and at 47g there is very little shell between your fingers and the internals, so it feels less substantial than it measures.
