In my use, the fan went mostly unnoticed. I don’t really have this issue, so perhaps I’m not the best test subject. It’s very, very subtle and I do wonder just how big of an impact it will have on users who do suffer from clammy hands.

It’s only when I try very hard to notice the fan that I can feel it. Unfortunately, the fan only spins at one set speed, which results in a soft blowing of air with very low noise. I was hoping for some different speed modes, to sacrifice quiet operation for additional cooling power. It’s a simple choice of on or off, which I was a little disappointed by. The other button on the base of the mouse controls the fan. Further customization can be done inside of the optional software, though most won’t feel the need to install this. To customize the lighting mode, there’s a button on the base of the mouse. It’s diffused nicely and looks fantastic, even in a brightly lit room. It might not be the main marketed feature, but the 360-degree lighting is very well done.

Though there is a black variant, I found the white really helped to show off the Zephyr Pro’s fantastic RGB implementation. I received the matte white version of this mouse for review. The scroll click, however, is a little stiff. The scroll wheel has clear increments and will work well for those who use scroll to change weapons. They remind me of the side buttons on the Logitech G Pro X Wireless Superlight, so the mushiness is obviously not a dealbreaker when you consider how popular that mouse is. The OMRON switches feel crisp and responsive and the side buttons are only slightly mushy. The Pixart 3389 sensor worked flawlessly in my use with zero tracking issues even during extremely twitchy gameplay moments. In the hand, the shape feels very similar to the Glorious Model O Wireless and I immediately felt comfortable testing it with Call of Duty: Vanguard and Apex Legends. On my scale, however, with the non-detachable paracord cable factoring in, it weighs closer to 75 grams. If it’s not obvious from the holes in its shell, this ambidextrous mouse is of the lightweight variety, shedding unnecessary plastic to hit 69 grams (without the cable). Before I discuss the fan, let me first quickly break down the rest of the Zephyr Pro’s set of features.
