My son, some years ago, was determined to buy a cheap radio controlled helicopter. The pictures on the box were so convincing to him.
He saved his money. I warned him this wasn't going to be what it is showing.
He bought it anyway. He was able to fly it twice. The first time only lasted 3-5 minutes.
He charged the battery and flew it again. Went out of range and got into trees and broke.
He was so disgusted. But learned a valuable lesson.
