Good valueArvosana 4/5
First impression is good. No installation problems and works as promised with Ubuntu OS (plug and play). I like the slightly matte surface on the top (right and left buttons) and the textured surface on the sides and scroll wheel for good grip. The on-off button on the bottom is shaped well and easy to switch on/off with short fingernails. It also gives a solid click feel when switching, so you don't have to look to make sure it's off. Overall build quality is cheap but for the price, you can't go wrong.
