Has anybody here ever used this device?

(The first YouTube video on the Celestron page illustrates how it works.)
Andrews has it at a relatively good price (for Australian standards).
Does it really work? If it works well, I might spoil myself for Christmas, although I had already bought a huge amount of books! I start to feel that terrible urge to buy...
EDIT: Apparently you have to use it away from metallic objects... so can I use it on my balcony if the railing is metal? I just tried a compass and it seems to work apart from when I am really close to the railing, almost touching it... I could also buy some fabric to cover up the railing I guess.
