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

I've owned 4 of these Microsoft 4000 Ergonomic Keyboards now. I love the keyboard, that's why I bought 4 but they are somewhat problematic (or at least they can be). The first 3 I bought each had the same problem.

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

Pros: Nice ergonomic feel. Solid feel. Not flimsy or fragile like some other keyboards I have had. Good amount of programmable short key buttons. Cons: Not a mechanical keyboard so you don't get the spring feedback. (new this before I bought though) Rear clip Broke on me.

Great features and easy to setup especially with the unreliablility of VISTA. Office users are happy and have switched from conventional keyboards to ergo keyboards.

The space bar is the reason I am returning this. This space bar does not work very well unless you hit it at the very bottom directly in the center. It also does not have a quick repeat because it is so hard to hit.

Comfortable Design; Great Features; Highly Compatible

Noisy; Unreliable Performance

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.

I've used microsoft's earlier version of this keyboard years ago. Between then and now I've used an assortment of keyboards. Several months ago I started using this at the office to make typing more comfortable. It has a negative slope design with the keys at an outward angle.

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

Ergonomically sleek; attractive and functional

Maybe a bit large for some smaller desks

I have exceptionally large hands and I find using a normal keyboard difficult. This my second purchase of this style of keyboard from Microsoft the first one lasted ten years. This new keyboard is as easy to use as its predecessor, but the improvements and additions are unbelievable and too numerous...
