Being a right-hander, I honestly don’t have the experience needed to tell you wrong-handed folks why you should buy this. Can lefties even skillfully play games on a PC?
Just kidding. (mostly)
Right now Logitech’s G903 SE Wireless Optical Gaming Mouse is on sale for $69.99 at Best Buy. If you or someone you love is left-handed and manages to overcome it in order to play PC games, they deserve an upgrade like this mouse will provide.
