I originally wrote a negative review for this toy....I have to take it all back! This is a wonderful toy, just follow the directions. First, there are little screws holding in the toy. The screwdriver is under the toy with the charger. The directions fail to tell you this piece of information. You will break the toy if you try to remove it without removing the screws. Charging and calibrating were cake and the drone flew well afterward. Our grandson will enjoy this. My husband and I were thinking of buying another for ourselves!
