SYBA CL-MS-046UP-BB Black 3 Buttons 1 x Wheel USB or PS/2 Wired Optical 800 dpi Combo Mouse with Blue Scroll LED Light - Retail

Works, smooth, cheap, feels ok

I hate the blue light. It stays on even when pc is turned off. Have removed from everyday pc and put this in a computer room where the continual blue light will not be an issue

Inexpensive, light touch, responsive, PS2 and USB is a nice feature. I have it hooked up to a KVM switch & it's working great

Kind of odd feel with straight sides instead of rounded but that's a matter of personal taste
