Kensington Mouse-in-a-Box

Kensington 72213 Mouse-in-a-Box Optical USB Mouse (PC/Mac)

I replaced the one component of my MacBook that I did not like: the Apple Mighty Mouse bluetooth.

I did not like it because it went through 2 AA batteries (maybe AAA!) a month and I did not like the way it tracked.

The Kensington arrived today and it is completely plug and play.
