This was a Christmas present for my 15 year old daughter. Before this drone, it had 2 helicopters, but the drone is MUCH better than helicopters! :-D Helicopters had pretty big learning curves and broke all the time. Most of them didn't last more than 3 months even with all the spares we bought for them. This little drone is POWERFUL! The propellers keep falling off (because she doesn't fly very well and keeps bumping into something) so we figured it would be a lot cheaper to just fly her indoors (she lost 2 propellers on our lawn the first time). the week). When propellers burst in a house, they're usually pretty easy to find. When children are playing with these fragile machines, it is EXTREMELY important to be able to buy spare parts! I searched Revain's website and was able to find ALL OF THESE replacement parts: propeller blades, batteries, bumpers, motors and charging cables. It is important to note that each of these blades has a unique designation: WHITE A, WHITE B, BLACK A and BLACK B. Each set of replacement blades you purchase will contain only ONE OF EACH of these blades, each with a specific motor, to which it must be attached, otherwise it will not fly! For more information, see the user manual. My daughter had been flying it for almost a week when her sister got jealous and decided to buy one with some of her Christmas money! :-D Let's see what happens. Either way, it's a great purchase, beautiful and durable, and the kids love it! :-)
