This keyboard is great. It connects seamlessly between 2 devices via bluetooth and can connect to a third using the USB dongle. My previous review said that you have to hold down the fn button to use the function keys (instead of the windows shortcuts) but I subsequently discovered that you can turn on / off the fn lock to avoid this. Absolutely no complaints as a result. I have been using the keyboard for months now and it is solid, comfortable, and super convenient if you use multiple PCs alongside one another.
