    Microsoft Natural Ergonomic Keyboard 4000


    Over the past 11 years, Microsoft Hardware has been evolving its #1 best-selling Natural keyboard with timesaving features and sleek finishes. Now, the company is excited to introduce a new Natural keyboard featuring a breakthrough ergonomic design, developed for the loyal users that already love split keyboards.

    Natural Ergonomic Keyboard 4000 has been expertly crafted to allow you to work in a more natural position. The new Gull Wing design features a 14-degree gable, a natural arc and a curved key bed - bringing the keys closer to your fingers to reduce reach and unnecessary motion, while encouraging a more natural typing position. It also comes equipped with an optional palm lift for a seven-degree reverse slope and a cushioned wrist rest that encourages better arm and wrist alignment. To view these advanced design features watch the Comfort flash demo.

    • Relaxing keyboard

      I have had one of these for about 6 years... my other one broke so I ordered another one off OS. I love this keyboard. It really does relax your wrist and shoulders. It will take a week or so to get used to but once you do, u can never go back! The old ones will feel like ur trying to smush something between ur breast the next time you use it lol I work a lot on the pc and I wouldn't be able to go as long as I do without this. LOVE IT!

    • My 4th one. Ergonomic fit is great!

      I've gone through 4 of these over the years. The ergonomic "fit" is wonderful for someone like me who works on computer all day. However, the less than "excellent" is because I'm on my 4th one for little quality issues, like the last one got a broken lift-leg on the backside, causing it to rock and not be the right angle. Seemed very flimsily made and so top quality is just not there. I would have LOVED to report here that I've only bought one.

    • still working to learn how to work this item

      This is an ergonomic shaped keyboard, very unusual. Takes a learning curve for a fast typist. I'm getting used to the different placement of the keys and the humped up design. I think it will be useful for preventing carpal tunnel, as advertised, since the wrists rest comfortably as you work. I believe I'll enjoy it. It seems well made and I trust Microsoft products. Give it a try.

    • Microsoft Natural Ergonomic Keyboard 4000

      My last keyboard was over 10 years old and it was time to replace it. This keyboard is very sleek. I still havent used all the features. When using this keyboard your wrists feel like they are resting on pillows. I would definatley recommed this keyboard.

    • Love this keyboard

      The ONLY negative thing I can say about it is the letters wear off, but I am a very fast typer and this has been the case with just about every single keyboard I have bought. But this one is extremely comfortable with the padded wrist wrests and the options are great..use them all the time. But a word of advice...this keyboard is for advanced typers who do not need to look a the keys to type. IF it ever breaks...I will purchase it again, no doubt!

    • Darn Good Keyborard

      This is the very same keyboard I have at work so I knew I would love it. It truly is an egornomic keyboard. The keyboard conforms to your hands not the other way around. I love it!!!

    • Top Notch Keyboard

      I was introduced to this general "type" of keyboard at a Med. Transcriptionists conference a few years ago. That keyboard was still different from this, but the woman who had it raved about it. When I found this one I had to try it out and OMG - the world of difference in ease of use and comfort was amazing - even from the first kinds of ergo boards. This one allows for the user to not only hold their hands in a much more natural overall position, but with the keys falling slightly downwards towards the back of the board, rather than upwards, everything is much more comfy. It didn't take long to get used to either. Once you get used to this keyboard style, you will not willingly go back to other boards.... they actually hurt you to use them. I have short fingers and still the number keys are not difficult to reach. Top notch keyboard no matter how you look at it. (When I have to use a laptop in another room or while on vacation - I take this keyboard with and just plug it in to that and wholla... I am a happy camper).

    • To love or not to love "Ergonomic keyboards"

      I believe I am in a minority of people who like the form of these keyboards. It fits the way my hands and arms angle, and I don't have to push my wrists toward each other to hit the keys. This keyboard has a build up toward the center so that the reach is easier with second fingers. The fact that it is wired is not a big deal to me, because the other qualities make up for the small inconvenience. I am much more comfortable on this type of keyboard and if I should need another, I would buy the same model. Microsoft was once again thinking of the consumer's ease and products being user friendly.

    • Ergonomic Keyboard

      I'm having alot of pain in my left wrist and thumb due to keyboarding use. The Microsoft Egonomic Keyboard 4000 is hard to get used to, BUT it gives my wrist the support I need. I'd give this a try if you're having similar symptons.
