A person who uses this for web browsing or document production, would probably not notice too much. Although a FPS gamer would probably go crazy in frustration. I used it with my Win 8.1 Pro O/S. I even installed the "Set Point" & "Unifying Software"drivers from Logitech online.

I have used the Wave combo for a couple of years and am still smitten with it. The size, shape, and positioning of the keys are the most natural of any keyboard I've typed on--as comfortable as that other "natural" keyboard, but far easier to adjust to.

This was a while coming and then has a US keyboard layout. So I now have to remember touch typing skills.

This wireless keyboard from Logitech features an angled key frame that's also wave shaped laterally to provide the most comfortable typing angles for your fingers, hands, and wrists. There is also an integrated wrist wrest to ease the stress on your arms and wrist during long periods of use.

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.

I received the k350 keyboard, but it work well. I received it in place of my order of a M550 but I look it up and i found no different. I got a good deal.

I have used this mouse/keyboard combo over and over again in any workplace I have ever been and its always been very reliable. Have never had any issues with overall functionality or pairing with other dongles. Its not a mechanical keyboard I use from at home but I still love it.

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.
