After using this keyboard at home for a month, I talked my boss into getting the company buy one for me at work. Since, I have had no problems with my wrists or hands hurting. I am very impressed with the Microsoft Natural Ergonomic Keyboard 4000. In fact, many co-workers also wanted the keyboard.

Padded wrist wrest; Great ergonomic design; Programmable keys

Keys are soft; touch typists might not like

An excellent product with awesome value. I have one at home and work and cannot recommend it enough.

I have this keyboard at work and it is just great; I like the spacing in the keyboard which forces me to use both my hands while typing; Multimedia keys for mute and launching programs are an added bonus; This is a wired version.

I bought this keyboard during an emergency. I had used this type of keyboard before but not from Microsoft. This keyboard is great! I love it! It is very comfortable and is easy to use. When it arrived, I just plugged it into my monitor and I was in business. Can't say enough! Buy it!

Affordable; Lightweight

Smoother Mouse Pad

The only issue I had with this keyboard was the compatibility with Windows 7. You can download the driver on the Microsoft website, so it's no big deal. I love everything else. The wrist pad is soft, the "my favorites" buttons are awesome, and the zoom button in the middle is useful.

Comfortable Design; Easy To Clean; Great Features; Quiet; Reliable Performance

Limited Compatibility

I am actually typing on this keyboard as we speak. I bought it about a week ago and I have to tell I completely love it. I love the simple style and ease of use. I was skeptical at first because of the price, but I wanted a new keyboard and didnt really want to spend a whole lot on a keyboard.

Great keyboard, fantastic for keeping your wrists comfortable while typing!

Ergonomically sleek; attractive and functional

Maybe a bit large for some smaller desks

Just a quick piece of advice for any gamers thinking of buying this keyboard. It's by far the best gaming board I've ever used. Forget so called gaming keyboards, this one os ideal for FPS or any other kind of game come to think of it.

Is not the cheapest of keyboards but their again it is not the dearest.Very good value for money and well thougt out and well done Microsoft.

Sound buttons are Excellent; Web & mail search, five extra buttons you can dedicate to what you want, zoom in togle for browsing and pictures; Back & Forward buttons for easier navigation & when working in word all the keys are there and just to cap it off there is a gell wrist rest which is...

The only thing I have found is that the space bar is not as soft touch as the rest of the keys

A great keyboard to use, buy it fails totally at the first split of water on the keys. The MS Comfort Curve 2000 is less than half the price and "Split-Proof". For such an expensive keyboard, would it be too much to make is split proof

Takes a bit of time to get used to it. but 200% prefers it now than the standard non ergo keyboard. Definitely gave my wrists the support they need. Helped ease wrist pain. Got 2 of same keyboard - one for home, one for work.
