I use this at work.
It's a great keyboard for me.I have carpal tunnel which limits my ability to use my pinkies for typing, but the curvature of the keyboard is very helpful.The wrist rests are helpful as well to put my hands in a comfortable position.Eventually, I'll buy one for my home.
This is a big issue because number "2" and "@" are very commonly used keys and having to go back to edit what you type (thinking that "2" registered when you pushed it) is annoying.
Great ergo keyboard with easy soft keys; the only knock I have is that the lettering on some of the letter pealed off from so much use but this is normal with all keyboards.
The 2 on the keyboard doesn't work very well.
It is now August 2017 and the USB connector intermittently malfunctions causing my mouse and keyboard to stop working.
On both of these that I purchased, the #2 key at the top of the linear keyboard malfunctions, and using caps lock also malfunctions on one of them.
This is a terrible keyboard for the simple reason that it doesn't stay connected to the receiver.
However, DO NOT LOSE OR DAMAGE THE USB RECEIVER BECAUSE YOU CANNOT BUY A REPLACEMENT, MAKING THE KEYBOARD AND MOUSE USELESS.
The dongle does not stay connected.
