Logitech MK550 Wireless Wave Keyboard and Mouse Combo

I bought this from Amazon when it was $52. The receiver is so power-hungry that it shuts down all other USB devices connected to the same USB hub. Using a powered USB hub solved the power issue, but the keyboard is so laggy that it sometimes takes 10 seconds to see what I have typed. I also do some light gaming, and certain key combinations just don't work at all. Not what I expected from Logitech.

very bulky. The print on key is faded quickly on my keyboard.

I don't have a problem with mine //@Anonymous: all logitech wireless keyboards are pretty bad .. so much lag and disconnect.. unless you put the KB few inches near the receiver. i tried 4 of them. all bad. they have good mouses but very bad keyboards
