Fasient1 Wired Gaming Mouse USB - 8 Programmable Buttons, Mechanical Switches, 3200 DPI, RGB Breathing Light - Ergonomic PC Gaming Mouse for Laptop & Desktop (Black) - Perfect for FPS, MOBA & MMO Games

The main thing I like about this mouse is that it fits really nicely in my hand. It's a claw grip, not a palm grip. Only had it for a day right now but for roughly £14 it's a great little mouse. However! As for the RGB Lighting effects this is where the mouse really falls flat. It's just a constant rainbow flashing light effect. So far I've had no dea how to change the lighting effect and it still stays flashing even after you power down your computer.I wish you could customize the lighting effect.
