Query: Great Board- used to be very expensive

Once you get used to this board, its great. I used to use this board in my office but never bought one for home because it used to be so expensive. All it needs is a cool blue light underneath the keys to snaz it up a bit. I gave it only 4 stars for ease of use just so that buyers will know that there is a little to get used to when you switch to an ergonomic board.
