Not much to say about this one. It's apparently branded Lenovo. No frills cheap $1 mini mouse, grab one if thats your thing.
EDIT: This is the mouse I received http://m.imgur.com/2a3wACO
MOD: Nowhere on the eBay listing claims to be Lenovo branded, other than the mouse OP has received, which is of different style than the linked mini mouse. Thus "Lenovo" is removed from the title.
Doesn't say Lenovo anywhere?
