Both Logitec and SteelSeries Rival (I got) are perfect mouses but they are bit overpriced for him. The mouses he's showing are about 10-30$.
As I told you on skype try to keep it simple and buy a mouse that will break in a month. The more accessories they have the more unreliable they are.

But if you wanna go to 60-70$ mouses yea, Rival is the way to go. Don't even think of buying a Razer one (shitty quality,good gaming quality.)

I got SteelSeries Rival 300 and its PERFECT. s/o to Rise for the help.
