Good mouse if not for the double left clicking that starts at about 6 months work these. I have one, but once I get tired of having to slam it onto my desk to make it stop double clicking, I'm going to replace it with a Razer.
The wired gaming mouse from Logitech sports an optical sensor with up to 25,600 DPI, eleven programmable buttons as well as adjustable weights, which turn the G502 Hero into a decent choice in the affordable price segment of roughly US$30.
