Actually a great budget mouse, I opted for this over Razer or Logitech and can't sense a gap in quality from my experience despite the difference in price. Overall 80 hours of Ultrakill later and I can vouch for it's functionality.Only cons I have are personal gripes due to large hand size - this mouse is pretty lightweight which I've grown accustomed to despite preferring heavier mice in the past, but its width and the way my hand has to grip it to have the side buttons accessible to my thumbs at all times does give minor cramps after prolonged sessions. For general use and browsing, it's fine and doesn't induce any discomfort so farBattery life hasn't run dry yet, despite active sessions up to 3 days; works fine wired, charges quickly and looks nice doing so with the included stand.Profile switching is a nice touch and is quick and easy to connect and reconnect via Bluetooth or the included wireless USB receiver.
