Good mice, good software, nice design, i am lefthanded, you can customise buttons, acceleration, mouse movement, DPI, sample rate, colors, customisable side wings is great, mice is perfect for casual FPS games, i was using high-end Razer mices for years, this mouse is fully comparable to 200E Razer mices...,and is ambidextrous, is pretty hard to find good ambidextrous mice, this one after fow hours of gamming i recommend!
