The annoying thrum that plagued the original is gone, and the fan positioning has been tweaked, blowing directly upward instead of at an angle. When it comes to the fan, it's far quieter than before and also less disruptive.

And for a mouse with actual moving parts, I'm happy to see that there's no rattling when shaking the mouse either. Build quality is good, and there is minimal flexing when pressing down on the sides. The geometric open shell design brings its weight down to 69g, and it feels a lot more nimble than the Zephyr. However, the mouse is quite large, which means that certain grip styles such as the fingertip grip work better for those with bigger hands.

It is a safe, versatile shape, suitable for almost any grip style. With a flat profile and slight comfort grooves along the sides and mouse buttons, it feels much better in hand than the Zephyr. It's now got a far more comfortable shape that's very similar to the Glorious Model O. The Zephyr Pro fixes a lot of the issues faced by its predecessor, and the improvements are significant.

One year later, Zephyr Gaming has rebranded to Marsback, and their new mouse, the Zephyr Pro, is here for a second shot at active cooling in a gaming mouse. Unfortunately, the mouse's shape didn't feel the best in hand, and the fan was noisy and buzzed frenetically when using the mouse. It had a built-in fan, blowing a cool breeze against your hand to banish sweaty palms. Last year, I reviewed a quirky prototype of a gaming mouse called the Zephyr.
