Product review (1 stars): Complete waste of money
This is just a cheap little toy and I didn't expect much from it, but out of the box it's impossible to control or calibrate. It flings itself toward the ground in a random direction as soon as it gains enough power to float. The propellers don't rotate in sync even when the thing is fully charged, freshly cleaned, and has four new blades. It is only frustrating. It did not work properly for even a moment, no matter how I tried to follow the instructions.

Complete waste of money. Do not buy.
