Logitech as we like it!
Multiple buttons, up to 25,000 DPI, indescribable swag with RGB, good size... The G502X is probably the best mouse I've had so far. You can throw it against the wall after a game of League, pair it with the RGB on your fans and even prevent your 8-month-old baby from eating the cable thanks to the wireless.
It's a good product that'll make you feel like a pro gamer even if you're losing 0-25 to bots.
