Pros: Works with KVM on linux and windows, Optical

Cons: slightly heavy, has odd texture on the bottom

Overall Review: I needed an optical mouse that would work on Linux, windows, and had a ps2 connector for my kvm. My kvm doesn't like usb - ps2 converters, so I got this. Works like a charm on both computers!

Pros: Tiny, VERY sturdy!!!, Large capacity, looks cool

Cons: is a little snug on some usb ports

Overall Review: I keep this on my key chain, and it never fails. Very convenient to have 8gb on you at all times.

Pros: Cheap , GIG, Low Power consumption

Cons: No velcro included

Overall Review: Works great, I have 2 daisy chained and transfer media, stream videos, etc with no trouble
