I have run this drone at least 20 times and it still works great. This ATV is very fast, stable and sporty. Very impressive. The only negative I can think of is that I've tried to find replacement props online and haven't been able to, but I haven't lost any yet. While this is just a precaution, it has 4 additions. I really wish the range was better, it loses range pretty quickly, I'm very afraid to take it far, I'd say I might get 50-60 feet before it starts doing its thing, which is usually in ends in a crash. All in all I really like this drone and would buy it again because I have 2, one to fly and one to cool down, not good for back to back work on the motors. It's definitely worth a few bucks more compared to other quadcopters to buy.
