Great mouse, nice RGB light, nice effect, great accuracy

Inputs took effect immediately, color variations and effects all worked, and calibration went smoothly

The cool lights and effects are appealing, but the quality control and longevity of these devices aren't worth it to me anymore

I love the light effects and being able to customize them for my preference.

I like the color effects but what I love most is the mouse wheel, its so perfect for me

And the lights add a cool effect

The Chroma is awesome and the effects are as well

The light is a cool effect and has software to make any adjustments you need.

Mouse works great with my 2013 iMac including the lighting effects configureable in Razer Synapse

, the "breathing" effect could be a bit faster, as it was just off for a while (probably so the lights could change color, but speeding this up would be fantastic) and honestly that's about it

The lighting effects are the best part about this mouse, but also where I knocked off two stars

Yeah, those neat lighting effects sure are worth the extra dollars

I love the new Chroma effects, though I usually have mine set to a static light

With 16.8 million different colorsto customize your mouse, comfortable sides, 2 extra buttons on the side, sensitivity changing buttons and a cool wave effect, this mouse is pure gold.
