Personally feel trouble, I bought it has not been much use, put a long time will be out of power, you have to charge, the connection trouble and no screen prompt, just rely on two small lights flashing there, not even connected to see whether the two small lights flashing, whether the keyboard is standby, Is it connected to the device, etc.,, just see the light flashing, trouble to 、、、、 and the shape is really not dee, a bit like parts removed from a computer, it is a little ugly, although it sounds good, Bluetooth keyboard, it is not recommended that you buy oh, used probably don't like, what else can you ask,
