The base must be plugged in and turned on. Touch the center of the base; if it is not hot (warm is okay) then you are good to go. Use your hands, supporting the Death Star in case it gets pulled down to the magnets, to find the sticking point - which will be located right where it is in the stock picture - where the Death Star is hovering half-an-inch above the base directly in the center. When the Death Star feels like it isn't being pulled in any direction and feels stuck to the center, let go.
This shouldn't take more than 30 seconds. If it seems impossible, it's because it is! The base has gotten too hot and you need to turn it off (switch is near the power plug on the base) and let it cool off for 5-10 minutes.
With that out of the way, this thing is awesome! It is almost worth the price just to have a floating Death Star in your house! The bluetooth speaker aspect is sufficient to fill up a whole room with sound and the sound quality is what you would expect from a 5 Watt speaker - about as good as the speakers on a good monitor.
The speaker charges via micro USB and can be charged while floating. The Death Star is fairly difficult to knock loose once it is in it's levitation pocket.
I didn't want to waste too much electricity having this thing levitate at all times... So I measured the power output from the wall with a Kill-A-Watt meter. 1.7 Watts! Assuming 11 cents per kWh, that's 13 cents to float for a month! (It does use more while the Death Star is wobbling, interestingly enough. Up to about 6 Watts.)
That settles it: There is no better purchase than a floating Death Star speaker.
