I bought two of these. The first was doing fine for the first minute or two and when I released the controls it should have hovered. Instead, it took off to the left and crashed 20ft up in a tree. It broke when it fell. I got another on a good deal and it lasted almost 5 minutes. It stopped responding to controls and started climbing and moving forward. It too crashed into another tree and broke. Approx $100 for two drones and I got about 6 minutes of combined flying time out of them. Don't waste your money.
