Question: Does the paint from the letters last more than two years?
Document: Additional versions are also available, such as a wireless version.I used a Natural keyboard for many years, and when it started failing I bought a Microsoft Keyboard 4000. Well, the 4000 keyboard has printed letters that wear off after a year or two of steady usage. Also, I never liked the spacebar, which required extra pressure to enter a space. It just did not feel right, but I got used to tapping harder for spaces.Finally I started searching for a used original Microsoft Natural Keyboard.
Reminds me of the old Microsoft Natural keyboards I used to get. I had two MS 4000 natural keyboards which the second finally wore out. It was refreshing to get back to this one. I was used to the 4000 layout after 8 years of use, but i like this keyboard better, although I am not used to it yet.
This appears to be a clone of the Fellowes Microban Ergonomic keyboard I've enjoyed for the last few years. I acquired that when I undertook an extensive writing project (a few thousand pages), as well as for daily use. It was invaluable.In recent months that one had started to get some stiff keys, some false double-hits and misses. My fingers started to get soreness too. I briefly went to the straight cheapo keyboard that came with my computer, but that seemed to only make matters worse.
I got spoiled having the ergonomic keyboard and when my last one died I had trouble finding a new one at a reasonable price. Low and behold, Amazon came through again with a great keyboard at a realistic price.
This is my third ergonomic keyboard. The first two are Microsoft keyboard and this is hands down the best! You won't be disappointed.
Very good. Reminds me of the old Microsoft Ergo, but 3/4 of the price. I ended up buying two. Works with my Linux, PCBSD and Mac. Nice job.
This keyboard does not seem to me to be truly ergonomic. Although the keyboard is split into two, the keys are hard to press, and make my hands get tired of the pressure. This is, to some extent inevitable with keyboards that have high keys, but seems to be worse in this one.
I have read some of the reviews and wonder what they expected at this price. I have only used this keyboard a few hours and I guess the best that I can say is that I ordered a second and will give two Microsoft keyboards to others to play with.
I've tried a variety of Natural-type ergonomic keyboards since my last remaining MS Natural Pro wore out. Fellowes, Adesso, Microsoft's current Natural 4000. Honestly, they're all pretty much junk ... except for this one.The Periboard 512B is a clean, compact design, VERY similar to the long-discontinued Microsoft Natural Pro. It isn't quite as smoothly rounded in profile as the Natural Pro was, but in all other respects it is pretty close to as good.
This product is nearly exactly the same, with probably higher quality keystroke action. I'm pretty sure the alt keys are farther from the center than the Elite was, but this isn't a big issue. Moreover, the spacebar is split in two, which is different, but very welcome (the action is VERY smooth with the spacebars).
Answer: I have had 2 of these keyboards for one year and I have seen no degradation in paint I have not had a problem with either of them.
