Ratings and reviews

Rated 5 out of5 by fromI can type without painOnly have had this keyboard 2 weeks, so far it is great. I have big hands and arthritis in my wrist. This is the only keyboard I found that I can touch type on without pain. My wife has small hands and is 90 wpm touch typist. She was amazed at how easy it was to adapt to the somewhat different layout. The force required to press the keys and the length of travel of the keys seems perfect. Some reviewers say it is cheaply built. Well, its a $50 keyboard. It seems far better than the $20 ones, better than some $100 boards, but not in the same league as the $200 keyboards. I think its a bargain at $50.

Rated 3 out of5 by fromGreat keyboard, but zoom and 5 hot keys don't workI really like this keyboard for the comfort and wrist support as I work on school work. That and it's wired so no batteries to worry about. But the zoom button I had counted on working never does, and I cannot figure out the 5 hot keys or the document keys. It came with no booklet of how to set them up, just a basic specs book. I'm seriously thinking if sending it back though all the other keys on the keyboard work. Maybe it's only supposed to work with new windows programs. I came here looking for a troubleshoot driver for it, and I'm disappointing to not find anything help wise on the site about it. Hopefully if you get one all the keys work, or you receive a book on how they work. From the reviews it looks like I was the only one who received a faulty one.

Rated 3 out of5 by fromYes, the painted keys are terribleThe keyboard is great, but as others have mentioned, the painted keys are terrible. I've been using this second keyboard for a year now, and the M, C, V, comma and shift keys are now just black. Many others are illegible. It's a shame that such a great keyboard is manufactured to such a low quality standard.In addition to the paint job, I'd wish for two more improvements:- I wish the keyboard wasn't quite as loud.- I wish it was easier to wash the keyboard without having to remove a dozen screwsFix these three things and it's a 5/5

Rated 3 out of5 by fromTime for an update: backlighted keysI've had this for a few years now. It's my third MS ergo keyboard, and the keyboard shape works for me as it always has. Downsides: the spacebar is not securely attached and is noisy; the key labels wear off over time, especially for people who use hand lotion or hand moisturizers. Also in a dark room, like you must have for photo or video editing, you can't see the keys. Backlighted keys would fix both the wear problem and the dark room problem. I am desperately searching for a new keyboard! The Yes to "recommend to a friend" is actually "yes, but with a warning."

Rated 4 out of5 by from5 Stars for Erogo-fit ONLYI purchased my first 4000 keyboard several years ago for around $150.00. The price is considerably lower now. Today the price is good for the value $40-60.00. I am pleased with the ergo design as my typing speed has improved and I can type comfortably for extended periods.On the down side, I have replaced this keyboard several times during approximately 3 years because the letters quickly disappear and other people ask "what happended to your numbers", and I I type by feel to this is an inconvenience when I need to know.I am hopeful that the numbers on the one I purchased yesterday will last for the life of the keyboard.

Rated 5 out of5 by fromWho buys a keyboard for the longevity of paint?All the one star comments because the letters eventually wear off because they're painted on? If you're burning the paint of your keys, I doubt you look at the keyboard while you type or at very leastthe layout of a QWERTY keyboard is burned into your brain. Yeah, I guess if you're buying a keyboard for the longevity of the paint, probably isn't the keyboard for you. It's a great keyboard otherwise.

Rated 1 out of5 by fromGreat Design/ Poor construction Keys are CHEAP!!!!Why would I put one star on my favorite keyboard?Well hopefully some day someone that can make a difference will read these one stars and realize Microsoft is missing a gold mine opportunity here.Microsoft obviously paid an engineer good money to design this keyboard as all the keys are in the right place and well thought out.Problem is I grew up on keyboards that cost well over one hundred and fifty dollars and the keys felt like it. If you go on any vendor site you will see similar complaints to mine.1. The print is painted on the keys instead of having the plastic actually etched or molded through so that we don't ever lose our printed keys. With this keyboard if you type a lot in time you will wear off the print to the top of your keyboard so that you can not see what your keys are as they will be black.2. While the keys are placed ergonomically they are far from being ergonomic in construction. It hurts your fingers to type for extended periods on this keyboard as the pressure across the keyboard is not consistent. Not only that each key has to be pressed just right. Hard to explain, but you will find out.Like I said at the top of this review. The Microsoft 4000 keyboard is my favorite keyboard. I don't see the difference between the business and residential model other than price though as I have owned both.The keyboard layout is perfect. USB connection to computer has no worry of delay or battery signals issues. And the wrist rest has not been cheeped on. I just wish the keys were manufactured to a higher standard.Microsoft is missing a golden opportunity here as people would be willing to pay for a quality product. I myself would be willing to pay two to three hundred dollars for this exact keyboard if it would last and not hurt my hands.
