Bests & Worsts Reviews from Amazon

Refuses to properly calibrate, flies on it's own, constantly drifts, very poor recording resolution, like 480p, flew away on it's own completely opposite to the directions I was giving it, like it was being controlled by someone else, and it took me an hour to find it. One of the batteries wasn't molded right and barely fit in the drone. I start the thing up, calibrate it like it says, set it down, push the stick forward for it to just lift straight up, and it will lift up about ten inches and then fly full speed horizontally at a random angle and crash into something. All I did was push the controller stick forward for it to lift straight up. It did this 9/10 times I tried to use it. I have never had a product that has failed to perform the task it is designed to do as poorly as this drone. This product exists only to scam people out of money. Can't find it to return it, can't get your money back. I will never purchase a Zyma product again. *update: I have gotten multiple emails from the seller begging me to take down this review. I will NOT be doing so.
