Bought this mouse because of the shape and all the buttons, and I really like it, but its too big for me.
And unfortunately for me, the shop I bought it off wont do a refund.
So my loss is your gain, this is a brand new mouse (used for about 5 days), you wont find one cheaper.
Ill provide a copy of the invoice for warranty purposes.
