I liked the way the Enigma look, and when i received it, it seemed like it was going to fly nice and smooth. Before they end of the first flight in mid air the blades hit together and broke like glass. So I returned it for another one, because when it first worked it seemed like it was going to be a very smooth running heli. So I asked for a replacement, and it just didn't work. The lights came on but the heli wouldn't fly. It looks cool and if I could get one that worked it seems like it would be a blast, but i decided to just go for the refund. I won't buy these helicopters again, and i have seven of them from various sellers.
