The software saves settings every other time. You can’t even play it, you can’t even work normally in Worde. Why huge resolutions are needed, I personally don’t understand, at 3200 it flies across the entire screen, so 1 mm is half a table flew by. Logitech used to make great gaming mice, before that it was wired - and now it's complete slag. Got pros: Logo, some built-in profiles, although I don’t understand why they are needed. Cons: The mouse is very uncomfortable, constantly slips out of the hands.
