I bought this mouse a while back in August from Newegg.
(1) They lost the rebate. No record at all when I called. I was able to fax in a copy and received my check about a month later.
2) I realize that picking a mouse is like picking a religion, but I prefer the Logitech G400 for gaming.
I tried if for about a month of gaming, after my old Logitech died. But eventually gave up
and bought another Logitech.
