Logitech� Wireless Wave Combo MK550, Dark Silver 4.5 5 67 67
Logitech Wireless Keyboard/Mouse Best Ever The keyboard and mouse are great. The keyboard has the soft touch keys I like, easy to navigate using the different options, and user friendly. The same with the mouse. October 13, 2014
Very Pleased I am very pleased with this keyboard and mouse. I like the feel of the keys when typing on the keyboard and the design is ergonomically correct. One of the better keyboards I have purchased. October 13, 2014
Awesome Keyboard I love this thing! This is my first wireless keyboard and I love it. love the wave design - perfect for my long hours at the computer, plus it came with a new wireless mouse! October 6, 2014
Works great! I would recommend this keyboard to anyone. It fits comfortably with my hands; it's extremely quiet which is a feature I was looking for; it has buttons for shortcuts that are completely functional. The best thing is that it is basically a plug and play. Be careful when unpacking the keyboard from the box. The USB, which makes it wireless, sits in a corner all by itself stuck in a little hole. I almost threw the box out. I think it needs to be placed with the mouse. October 6, 2014
