Review on 📸 WiFi 4K HD Camera Live Video RC Quadcopter with Altitude Hold, Gravity Sensor Function, RTF - Perfect for Beginner Flying Experience (Drone) by Crystal Lawson

Bought for my son for his birthday (he turned 12) and for use in building a house. We got used to the drone via YouTube as all the instructions we received were in Chinese. We practiced with it in our garden and found out how it works. We used it for the first time today. I saw my son controlling it. I asked him to keep it at about 25 feet while I took some shots of the ground and site. When we started shooting it down, it turned out that the signal was interfering with it. The drone literally took off in a different direction. As my son chased after him, it became quite apparent that he would not be able to regain control. It's gone. I don't know which was worse seeing my son crying because his favorite birthday gift was lost through no fault of his own or the fact that I just spent $70 on this item and it was gone. Forever and ever.
