It turned out to be very strong, the son is 4 years old and he once 50 times a day breaks everywhere, but for a week everything is whole. Thought for the first day everything will break. There is one spare screw. Batteries last for 20 minutes
Super helicopter! Handling as good as drone should. IR wireless controller works from any angle. I happy with this buying. Recommend this toy! The package comes quickly enough and was little damaged but all is ok, the box is much bigger than toy inside and save it.
