Taken in by a child of 11 years without any problems. Charging by USB is very environmentally !! For longevity, it will be no doubt, but the general construction seems good enough to withstand small crash. The flight time of 7 minutes is a bit short order (it cost a star, that!) But charging is fast enough (about 40mns). Good fun! 16/08/2012: After 6 months of a bit of fun, I completed the comment: FRAGILE !! Despite all the attention that can make a child of 12 years in use, hovering is not possible ... it constantly spinning in hand, despite an exchange of wings, a repositioning of the battery and Review all screw tightening. Back in not guaranteed, since the original case was destroyed (this is common with children!). The kit of "fitness" cost almost the price of the unit. And no guarantee that the problem is resolved. So end of the adventure! It's a shame ...
