Buffalo - Use your favorite keyboard and mouse for other devices
This tiny USB look-alike device, which will be released by Buffalo in early November, enables your PC's keyboard and mouse to be used for other devices such as a tablet, smartphone, and other PC.
It is a Bluetooth HID transmitter - "BSHSBT04BK" - and it is compatible with Android smartphone, tablet, Windows PC and Mac (For iPhone and iPad, it's compatible with only a keyboard.)
You can use the keyboard and mouse that you are used to use for other devices (maximum 10 devices). You can even control a Mac with your Windows PC, and vice versa.
Communication distance: maximum 10m
