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

I decided to purchase this keyboard for the ergonomics and the fact it uses the same unifying receiver as my Logitech MX Ergo trackball, so I could free up a USB port. Have had it for about 3 weeks now and am slowly getting used to it.

Amazing ergonomic keyboard and mouse set. The keys feels kind of mushy, as do all membrane keyboards, however the handrest and the keyboard's shape make for a very comfortable typing experience that lets you type for hours without any fatigue or discomfort.

Would highly recommend, top quality and doesn't need drivers for Windows 7 or 10.

I bought this same set two years ago, and even with heavy use it still works perfect; Also, the battery life on both of them is great; I ordered another set in case they quit making them, they are that good

The padding on the wrist rest on the keyboard started coming off after 2 years; a little glue fixed it right up

Earlier this year I bought the Logitech 520.....a flat keyboard. I HATED it. I kept making mistakes and misplacing my fingers for months. Finally I chucked it and went for this Wave, which I have owned before. Perfect key positions and feels so good not to keep making errors.

Boasting a slightly curved, contoured keyboard and a smooth, substantial mouse, the Logitech Wireless Wave Combo MK550 could be just the thing for...

Curved keyboard design helps to keeps wrists straight; Padded palm rest; Smooth; substantial mouse; Plenty of hotkeys and programmable keys

Loud; cheap-feeling keys; Mouse buttons designed primarily for righties; Contoured keyboard design won't be for everyone

Boasting a slightly curved, contoured keyboard and a smooth, substantial mouse, the Logitech Wireless Wave Combo MK550 could be just the thing for typists with aching wrists and tendons, provided you warm to the wave-like form factor.

Keyboard and mouse both seem to occasionally disconnect and takes up to 30secs for it to reconnect again. Keyboard also doesn't like it when you press multiple keys simultaneously - also not good for gaming, as keyboard can disconnect at the most opportune time. Wouldn't recommend or buy this again.

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.

Works great as expected for my basic use. Still trying to assign the photos key. Using this device with a Dell Inspirion 5535 laptop and thus far it has functioned very good. For the price the quality is decent and should hold up to normal use.
