Arrived nice and quick. Works as described. Really happy with it so far

this is a great keyboard and the mouse it comes with is pretty good itself aswel. bought it for the wife to play mmo's more relaxed and it does just that. nice big keys and the restpad is well placed and spaced.

I do a huge amount of typing in my business and have stopped buying other ergonomic keyboards as I consider these keyboards far superior. The USB connection is extremely good with no lag and it's out of the box and able to be used in seconds and very comfortable to use. I have just ordered a new one for my employee.

The key-board is precise and accurate and has a 1970's-80's ‘electric typewriter’ feel to it which I prefer.

I bought this product as I am studying and therefore typing a lot! I love that it is wireless, so no more painful cords, and the lay out of it makes it so comfortable to use for long periods of time. Wish I had got it sooner!

It appears that the designers of the Logitech Wireless Wave Combo MK550 put all their focus on making the user happy when they set out to create this wireless keyboard and mouse combo.

The primary attributes of this combo are comfort and ease of use

The keyboard is large and bulky and may be cumbersome to transport

I bought this keyboard and mice because the keyboard has lots of extra buttons for quick access to applications. The ergonomic design is very good and it is very comfortable. But if only the wireless signal would not lag this would be AWESOME!!

The keyboard is about a foot from the tower case and the mouse about 2 feet. Operation was erratic with the sending unit plugged into the back of the case though they work just fine plugged into the front.

While the keyboard and mouse have plenty of features, I bought it mostly for the keyboard's ergonomic design. I absolutely love it! It took a couple days to get used to the curves of the keyboard, but it was well worth the bit of awkwardness in the beginning.

both keyboard and mouse function quite well, easy setup and use. Only major drawback it the the overall bulky size of the keyboard. Much to large for many keyboard slides.
