The key board is OK - nothing special worth that amount of money. The biggest drawback is the "mouse". It is so small so as to make it useless and I still use my regular mouse anyway. The feel of the keyboard is good (although it arrived with one key off). I had trouble making the software work with my previous Logitech devices already installed. Since neither keyboard showed up in the software, I had to uninstall it but it wouldn't take both of them, which it should be able to do. The look is nice and charging unique. So it's OK but nothing that special nor worth that price.
