Logitech Cordless Desktop Laser MX 3200

Keyboard unusable after some time – At first everything was great. Keyboard was slick and typing on it felt very good but after 1 year keyboard became unusable. Typing is crazy hard (keys are very sticky - even after cleaning). And on the far left side of the keyboard there is touch-sensitive slider which I've never used but it is very irritating - many times I've rested my left hand and accidentally touched the slider (which can't be turned off) and, for example, whole webpage zooms out.

Mouse is great and good for gaming, no problems with it. Mouse feels very nice in hand, good for gaming, keyboard has lot of handy features Expensive for what you get, irritating touch-sensitive slider, sticky keys after some time
