I bought one of these a while back when they were $25.00, and I'm not displeased, given that gadgets of its type have been known to go for as much as $100.00. But I must say MOTA's marketing is a bit over the top.
First of all, the toy is by no means, "Indestructible." In fact I managed to destruct a couple of the propeller blades (for which MOTA graciously sent me replacements).
Second, the box claims it can fly inverted. I can't begin to imagine how this is accomplished, given the physics involved, and have made no attempts to try.
Third, the thing is made very cheaply, and my copy's "sphere" is out of true. As a consequence, it doesn't hover in a stationary location, but drifts lazily backward. I've learned to simply accept that as its normal forward velocity, and fly it around like that.
For those who have said the controls aren't very responsive: RTFM. The control link is infrared, not radio. You must maintain line-of-sight contact between the controller's emitter and the toy, or you will lose control. And make certain the batteries in the controller are fully charged; weak batteries will reduce your control range.
Despite these drawbacks, I consider it a good purchase -- a frivolous novelty I fly around the office when I'm bored. You could easily spend $20.00 on less amusing things.
