Input:
I purchased this keyboard when my old one of this design didn't want to work correctly. This one is a little smaller than the older one, but fits in the keyboard shelf which was designed for the older one. The keyboard works well and the placement of the keys is easy for me.

Very happy I purchased this keyboard. It was just what I wanted.
