Microsoft Natural Keyboard 4000 for Business 5QH-00001 Black 104 Normal Keys USB Wired Ergonomic Keyboard Microsoft Natural Keyboard 4000 for Business 5QH-00001 Black 104 Normal Keys USB Wired Ergonomic Keyboard

Pros: I loved this keyboard. great design. very comfortable. easy to use.

Cons: My first one lasted more than 3 years. Several months ago, I finally replaced it. that one lasted about 6 months and I blamed my kids for its failure but the new one lasted less than 2 months. The forums say the metal that makes the contact is too thin and breaks creating a bridge or shorting out some keys. Very poor quality. Shame on you Microsoft for endorsing this manufacturer.

Other Thoughts: I wont buy another one. I'm typing this, angrily, with my mouse and on-screen keyboard until I find another ergonomic keyboard worth my money. out of newegg replacement warranty and I threw away the box. never did I ever think "A KEYBOARD" would drop dead in a matter of weeks. unbelievable.

Pros: It's a nice Keyboard, my old 4000 failed after years of use so I got another one.

Cons: I don't know if they take the pics that show what your supposed to get with it, but I didn't get anything but the Keyboard and I guess I should count myself lucky I got that at least.

I didn't get the user disk or manual but thank my lucky stars I got my limited warranty booklet, I'd be lost without that.

Other Thoughts: I should count myself lucky that it even works, I don't know who or what they have in their packing and shipping dept. because like a damaged motherboard that was put on top of packing materal and then taped the box shut with NO PROTECTION TO THE PARTS INSIDE it's a wonder anything people get from Newegg works. I had other problems with newegg and decided to deal with ASUS directly with my last Motherboard order and got that one fixed. I still had to pay a nice shipping fee on top which I'll never forgive Newegg for.
So I'll give a generous 2 out of 5 rating.
Newegg, Please send me my user disk and owners manual for this Keyboard!!!!!!

Pros: Ergo, Price... Features, I guess (I don't use them). I also like the black color.

I really like the attachment that ads more tilt back. I can't see some if the keys because of the angle, but I don't need to and for me that option is comfortable.

I can't complain about the key pressing. I like the feel or am just used to it. I type between 40-70 words per second, depending on content. I also use a lot of hot keys in excel and PowerPoint, number pad, etc. keys register consistently, no double taps and everything seems very accurate.

Cons: Like other users, keys failed after some time. The letters are worn off the keys. Home row and popular keys are invisible.

I have had it go missing on occasion from the device list (not working) on boot up and maybe coming out of sleep (after a new OS load and before I disabled sleep). Unlike others, I always assumed that was my desktop USB network (Asus P6T Delux v1 and like four hubs with scanners, printers, cam, external daddy's, USB drives...) the keyboard is plugged into my dell monitor hub, so I just hit the power switch off/on the monitor and the keybd works again.

It is worse with windows 8. At the dual boot screen, My mouse (logitech MX Anywhere (silky org@sm)) or keyboard don't get recognized for like 20 seconds. That is around half the total boot up time.

Problem happened on Win7 too.

Other Thoughts: Ten years ago, I got the "white" version, probably the original. I still have it hooked up to a server that I almostly access remotely, but it still works. It is a bit more clickety than the new model, is dirty and yellowed from age.

About four years ago, I got my first one of these new black ones. It died of key failure - first the left shift key (hot keys). I figured maybe I was a little aggressive. I tried to live with it for a month, but it was driving me crazy and then another key failed. So now I am on the second one and somehow I have a brand new spare in the closet.

The second one is still working great, but as I said, letters are worn off.

I've tried the spare and it is only barely more "fresh". The second one is maybe slightly broken in, but maybe only in perception.

So after enough use to wear the letters off, the action is virtually the same.

Maybe I should have given it five stars. The worn letters perhaps could be etched or embedded, so the paint doesn't wear off and even if it did, still visible.

Pros: All of them

Cons: Only if you are an IDIOT

Other Thoughts: Get one no two no three they will make you happy all day long.

Pros: Well laid out keyboard BUT it keeps failing to work upon random boot ups.

Cons: The 4000 keyboard has some kind of flaw that causes it to fail working at boot ups. I have searched the web looking for a solution but to no avail. I have downloaded new copies of the driver and reinstalled it many times. Nothing helps. The darn thing is dead about 1 in 10 boot ups. This is very, very annoying and disappointing.

Other Thoughts: It amazes me that Microsoft cannot produce a product that works.

Pros: Comfortable, well layed out split-keys board.

Cons: Not reliable! First one I bought had keys stop working after short periods of time ('A' after one week became intermittent, same with the 'L' after four weeks). Returned it for a new one. Different keys became intermittant, then quit. Don't waste your money on this keyboard.

Pros: Extremely comfortable, durable, quiet.

Cons: I've have have 3 of these suddenly die, the C key quits working to be more exact. Since MS has a decent warranty though it's not a super big deal.

Pros: I like the divided and highly curved key layout. I'm a big guy and it is frankly more comfortable to be able to angle my hands this way.

Overall touch is good, different than the Logitech boards I've been using, but good, positive key feel.

Cons: The attached wrist padding is somewhat slick, requiring frequent relocation of my hands.

Also, the space bar, un-like all the other keys, makes a loud CLACK when pressed. Considering how often the space bar gets used, it should be much quieter.

Other Thoughts: Quick look review:
My first impression was size; this sucker covers a lot of acreage. That isn't a problem for me but it might be for others. Also, the space bar noise could be a problem in an office environment.

Pros: If you have large or long hands and need a real ergonomic keyboard, this is it.

Cons: Don't let this thing get wet or even damp. Moisture of any kind will put this keyboard in the garbage instantly.

Other Thoughts: I am now on my tenth keyboard in as many years. I really want the old Microsoft Natural Keyboard back, they worked forever!

Pros: comfortable, long lasting, easy to use, good amount of options, good quality

Cons: Legs broke on mine

Other Thoughts: I have had this keyboard for more than three years. I have played MANY hours of FPS games, eaten a ton of food over it, and have typed an absolute crazy amount on it. Keys still work great, letters on the keys show NO wear at all, and even though it HAS to be filled with Chips and other assorted foods, still works as good as new. The only place that you can see wear is where my wrists sit on the key board...VERY good quality...totally worth the money.
