Microsoft Natural Ergonomic Keyboard 4000 for Business - Wired

Worked great for about a year. Now the number pad doesnt work. Even though the Num Lock is on, the number pad is intermittent. I will be keying in numbers and all of a sudden it will stop working. Contacted Microsoft within warranty period and they said this hardware issues is not covered under the warranty of the product. Do not understand that at all and am very frustrated. I will be ordering a different brand.

I got this for my mac computer and it is compatible. This is not very pretty, especially compared to the imac, but my carpal tunnel / tendentious got soooo bad, I had to do everything that I possible could to relieve some pain. This keyboard did help with my carpal tunnel pain, but it started to not work at all after a few months. I had to unplug the usb connector a couple times at first, and it seemed to work well again. But it started getting glitchy here and there after that. So, it is not terrible, but I do expect a product like this to work smoothly for at least a couple years. But-- surprisingly, it did help me with hand / wrist pain. I actually live with extremely severe fibromyalgia and chronic fatigue syndrome (me/cfs) and it has left me with an enormously sensitive body, always in pain and unbearable exhaustion, without relief. So, I really know the difference between placebo effect and actual, real physical relief. Along with this keyboard, I really struggled with finding the best ergonomic mouse. What I ended up realizing is that TWO MOUSE devices were the best for carpal tunnel pain issues. Here is the reason: Repetitive movement and positioning is what hurts the hands / wrists / arms so much. So-- If you constantly switch your hand / wrist positioning, you dont give the carpel tunnel channel enough time to start swelling and then pinching and then that horrible stabbing pain.. I had gotten to the point where brushing my teeth or holding a mug was unbearable. It was very scary, and honestly, depressing! It all started in early adulthood as well, which was especially depressing on many levels for me. I went to hand therapists, I had physical therapy, everything.. Still, I had so much pain. Now, after switching my desk equipment, I am 95% pain free! I seriously SERIOUSLY never thought that I would get pain relief. The key is to have an ergonomic keyboard (the slight difference in angle is enormous) and to have two differently-shaped ergonomic mouse devices connected all side-by-side. Here is the more expensive mouse that I purchased from Amazon: 3M Ergonomic Mouse, Optical, USB/PS2 Compatible, Small Size, Black (EM500GPS) *Be aware of the size for your needs! (S,M,L) Plus this mouse which was less than $20: Logitech Trackman Marble Mouse *One size fits all One other random thing that helps me, is something that is an all natural supplement used as a natural allergy treatment alternative. It is called D-Hist, and it uses a few all natural anti-inflammatory ingredients. The side bonus is that it helps with pain in the entire body -- and helps with allergies (at least for me. I had never heard of it before Amazon) Here is a link to D-Hist as well: Ortho Molecular Product Natural D-Hist -- 120 Capsules ~Just a quick disclaimer: I do not receive any money or any benefits (outside of personal happiness) from going through the efforts to lay out what has helped me in a VERY VERY VERY LONG journey of serious hand and wrist pain. I am not a medical doctor either, just a regular person, wanting to help fellow sufferers / survivors! Good luck to you all!

PRO=Its lot more comfortable typing on this than the old-style keyboards; NEGATIVES= 1) KEYs and SPACEBAR LOUD, distracting; 2) As others said, the ZOOM function does NOT work at all; 3) NO MANUAL OR FUNCTION INSTALLATION CD included, so have NO IDEA what the numbered buttons above the F buttons do Note: I found the manual online and even THAT does NOT say anything about those buttons); 4=The spacing ON EACH SIDE of some of the keys are slightly different (i.d., from F to B below it awkward to hit, keep hitting G). The 5th problem is only for watch or Fitbit users: Your watch hits right on the rest area making it uncomfortable unless you change watchband position.
