Similarly, the fan switch can be used to turn off the fan when you no longer require it. The light switch can be used to cycle between built-in RGB presets as well as to turn off the LEDs completely when held. Underneath the mouse, you will find the same honeycomb design as on the top, along with the sensor, and the light and fan switch. Of course, the fan is RGB-laden as well to complete the overall look. I prefer such an implementation of RBG lighting as opposed to something that is gaudy or loud, as it gives the device a touch of sophistication and it also shows that the designers have put some thought behind it. It also has a thin line of RGB strip running from the front side of the mouse curving all the way to the otherside, giving it a distinctive look. The scroll wheel remains constantly lit-up, which doubles as an indicator of the DPI profile that you are currently using.

There is plenty of RGB to go around here. The 5.9-foot cable is also covered with a soft cloth-mesh cover which should offer a largely drag-free experience based on your setup. The body construction is both grease and fingerprint proof, which along with the fan, ensures that you have complete control over the mouse while gaming.

Marsback has made considerable efforts into making the Zephyr Pro as comfortable as possible. I quickly got used to the shape and weight of the mouse (coming from the HperX Pulsefire Haste), and I was up to speed within no time. I have spent nearly three good weeks with it, and I have had no complaints. The mouse is slightly larger than other ultra light-weight mice I have tried before, but it’s not too bulky or long that it would cause any sort of discomfort.

The design is used to cut down on the weight of the device, but it also cleverly works in showcasing the tiny fan tucked away under the palm, which glows pleasantly along with the rest of the device. The Zephyr Pro is a handsome device, although I am aware that its unique honeycomb design might not be up to everyone’s taste. With a solid light-weight construction, RGB bling, and powerful PMW3389 sensor onboard, the Zephyr Pro is also a fairly solid gaming mouse that easily competes with the best out there. And what’s more, it actually works - in a sort of a limited capacity - but thankfully, it’s not the only thing Marsback is relying on to attract potential buyers. The fan is the Zephyr Pro’s biggest USP, because as far as I know, no major peripherals manufacturer employs such a solution to aid gamers like me.
