8 hours a day and more every day, .............

after which I now years had the ergonomic keypad from 1995 and this threatened slowly give up the ghost, after 3 years hard work I've been looking for a new natural product. The market for ergonomic keyboards is unfortunately not so great, so I'm back ended up with MS.

Microsoft Natural Ergonomic Keyboard 4000!
I must say I'm impressed. One has the pedestal at the front of the keyboard first removed the keys are very smooth, very quiet in contrast to the old and the Handball cushion is a very pleasant thing. The shape of the keyboard has been enhanced so that they better "in hand" is when the old Naturalkeybord of MS. The price of the keyboard will regret no one who read a lot or have to write.

This is not the keyboard for gamers of Renner, should be clear.

I have the Microsoft Natural Ergonomic Keyboard 4000
now for 4 months in daily 8 hours of continuous operation at work. There are no weaknesses can be identified and it has also been used to fast on the keyboard, even for a beginner for the Natural Keyboard. But each of the not write me 10 fingers or want to write, was discouraged by the keyboard. What has already been mentioned here that could wear out the letters, I can not confirm.

It is now for 6 years ago I bought the keyboard. WOW ....! What has now everything behind, and yet not to wear, no louder the keys, no key hanging, no abrasion of the font on the keys. The only thing that einzelen letters that are more needed to shine a little.
So I guess you can say, like a top device for a top prize.
