Bought just the mouse mid August for $44 so this seems like a decent deal. My only gripe with the mouse is it's quite small after coming from a logitech trackball. Considering I have small hands I find the fact that even after 5 months I still think the mouse is small a bit odd. It doesn't come with 2 different sized "shells" just different textures, one is smooth the other is rough. Hopefully the dumb COD crap will rub off soon.
You can try to use alcohol to rub it off...
This bundle is discontinued. The keyboard isn't mechanical either. Seems pretty good but I'm out of $$
