I was disappointed with this mouse and returned it to Costco after using it daily for a couple of months. The ergonomics were miserable, and using the buttons was awkward.

Google Checkout Sucks, can't cancel order just a minute after place. Cannot check purchase history at buy.com, it does not appear. Very hard to return with google checkout, it's not worth the $10.

#2, waddaya want for $10 off $30? Granted your points are very good as to whether people would use GC when they have other options and no financial benefit, but you should have known this mouse was junk because it comes from a company that conceptualizes and advertises more than actually listening to customers.

This mouse works fantastic on a mousepad or smooth surface table, however unlike regular optical mice the laser in this mouse does not work well on say.. the couch pillow, or on your jean and other such surfaces. Plan to use it on your desk only.
