This little keyboard is very handy and makes a good impression. The cover snaps magnetically into the actual keyboard and protect them safely at any transport and can easily be switched on and taken off. The unit was with me immediately on Nokia Lumia 2520 - recognized - a tablet with Win 8.1. It works great, and I can write with 10 fingers blindly, although it is of course much smaller than normal keyboards. Since this is connected with Bluetooth, remains for me still the USB port free for a nano receiver for a small Microsoft Wireless Mouse. I think all in all a pretty successful combination: small and almost a notebook.
