This item was a bit of a problem at first. I called the company and they assisted me in getting the powerball to operate correctly. I have a small hand and the speed and power of this powerball is such that it almost wants to fly out of your hand, so don't stand near anything breakable until you are able to control the unit. I would say this, don't bother with the docking station. It's a big waste of money!
