Microsoft Natural Ergonomic Keyboard 4000

Pros: - Ergonomic - Inexpensive - Lots of Function Keys

Cons: - Difficult to get Function Keys to work - Takes a little getting used to

Overall Review: I got this keyboard at a greatly reduced price as a Shell Shocker deal. At normal price, it is still a pretty good deal. I was not expecting much from it, but I ended up being pleasantly surprised. In terms of ergonomics, this keyboard is really nice. It feels very natural to rest your hands on. Rather than being raked toward you, the keys slope down as you go up the keyboard. It took me a while to get used to the keyboard, but I now really like it. The keyboard has a lot of function keys, but I had a rather difficult time actually getting them to work. And still, they only work on the rarest of occasions. However, I have always had issues with function keys, and I did not purchase this keyboard for the function keys. Construction quality isn't bad, and the keyboard seems durable, but I do worry that the rubber domes will wear out faster than I would like them to. Overall, this is not a bad keyboard. If you do a lot of typing, you owe it to your wrists and hands to try this thing out.

Pros: Super comfortable to use. Easy plug-and-play with Windows 7. Nice amount of quick launch buttons. The design looks nice, too.

Cons: The spacebar is the biggest issue. It is hard to press, unless you hit the very bottom-center of it, and it is a little noisy. Also, the letters on top of the keys faded really fast. I know I do a lot of typing, but other keyboards of mine have lasted years longer than this one without fading.

Overall Review: A solid keyboard for those who type all day and want to avoid carpal tunnel and cramps and all that bad stuff.

Pros: We have a couple dozen of these. No complaints. Keys feel good. Would recommend

Cons: None as/of yet.

Pros: I made my wife get one of these because of hand pain from working on pc all day and it relieved it, so I bought one

Cons: None

Overall Review: It does take time to get use to it but after that it's fast to use , my wife said it only took her about one day to be perfect with it. Others at her office tried it and ordered them also now. I see postings of where they lose some function in a year but I decided that if it cures her pain in her hand that is worth it. She has had hers for about 3 months w/o problem in hand or equipment so far and alot cheaper than a doctor

Pros: This thing is absolutely comfortable. The keys are angled perfectly with a nice soft wrist rest perfect for hours of typing.

Cons: None

Overall Review: I love this keyboard so much it's hard to convey just how great it really is. If you really know how to type properly this keyboard is perfect. When you put your hands down on this thing they keys just fall in line with your hands natural position. No need to angle your wrists. Think about it, with a standard keyboard you feel like a T-Rex with these stubby arms sticking out trying to type. On this, you set your hands down and it just flows naturally. It really is amazing. It will change the way you type and can alleviate stress and discomfort from lengthy typing sessions. I love it, you will too.

Pros: This is by far the best keyboard I have ever used. I have a bit of carpal tunnel, and have used a split keyboard for years. This one shines over all the others. The downward angle keeps my wrists straight, the palms rests are comfortable, and now I use the little back key in front as a habit - can't go back. But beyond the ergonomics, the key pressing is so smooth, it's amazing. Your fingers will literally feel like they are gliding as you type. Whether you use anything else, the key press alone is reason enough to use this. I don't use the new keys above the numeric pad, just out of lack of habit, but I love that the six insert/home/etc keys are in the standard configuration (some extended keyboards are rotating the arrangement). The mute and calculator keys are handy (reassign the calc to a better program), but I only occasionally remember to use the other keys up top.

Cons: Just two nitpicks: I use the F keys as F keys, not as the alternate functions, so I'd prefer the F label to be on top of the key instead of the front, to make it easier to read. Also, the number 6 key is on the left hand, which is a change that took some getting used to.

Overall Review: You'll never use another.

Pros: my large hands love the split keyboard with raised center.

Cons: the letters are painted on and not incised into the keys, unlike the previous model. The letters began to wear off within just a few months. After three years daily use, the letters are so worn off that only a touch typist can use the product. And then one of the non-mechanical keys failed, so the keyboard is toast.

Overall Review: overpriced for what you get -- updated 6/11/2016 after product failed in use

Pros: It's just really nice to use. Best keyboard feel I've ever used. Additional program buttons and customizable buttons is nice. I use the SILVER buttons ALL THE TIME.

Cons: Reliability. These keyboards do not last. Period. I've used these keyboards for about 5 years now. I've thrown 2 out from keys dying, and 1 needs to be thrown out because 80% of the keys have no markings. . • Apparently random circuits go out which affect a number of keys accross the keyboard. You'll just be working one day and a half dozen or so keys stop working. • Letters rub off WAY too easy. You'll have blank keys within 6 months (if you're a heavy typer like myself).

Overall Review: I will still continue to use these keyboards for as long as they make them, just because they are that comfortable for me to use. I love them. I REALLY wish they were more reliable. Prior to this line of keyboards, I had the old cream color Microsoft natural keyboard with black letters. I used that keyboard for about 6 years and never rubbed any keys blank, or it skipped a beat. I don't know why they can't make these keyboards like they did back then. . I keep a spare on on hand now in my hardware closet for "when" one goes bad on me, I can replace it immediately and not have to wait (and I know I will too).
