See video on Amazon.com Mignon is the first word that comes to mind when you discover this keyboard !! Indeed, I could not resist to present you the summary in this video, know that I am under Seven 64 bit and no problem with the installation. I find that the mouse buttons are very well placed and not spoil anything, just a button under the mouse ball allows direct access to the post travail.Bref, this keyboard worth it in my opinion !!
