These things are amazing right out of the box. Now I have 8 of these lol and only 1 failed. This is from the days of solid use. You won't find a better deal for a drone with these features and good customer support. Extra props and battery included, really great buy. I think that's why I buy them for all my friends. You can literally tie as many as you want with no hassles or obstacles. Perfect for kids and adults!
