Title: Just plain bad
Review: This is easily the worst mouse I've ever had. The tracking is very lazy. My old Logitech mechanical mouse tracks better.The worst problem is the scroll wheel. The wheel has a delayed action. It waits till you are typing then whiz! The page scrolls away. I'm not even touching the stupid mouse when it starts scrolling.I noticed people complaining about the sticky scroll wheel. I vivisected this POS to see why. It is simply a bad design. there is no space between the wheel and the housing inside the mouse. Dust and dirt collects off the wheel quickly gums up the works. You could clean it, but it's not worth the effort.
