Ansich works the device but it has decent Makken. The USB cable is too short, had to buy extra extension. The cover for the 2nd battery is quite shaky and almost broken out because the joints are already so thin. HTC Desire HD is placed on it and after a while then matches the original charging cable is no longer quite as good in the phone jack, which means that the charging plug in this device somehow the phone jack "bend" ...... So I would still look around for another device and possibly raise some extra money for a proper dock ....
