Bought these as a birthday gift for my 8 year old grandson and I charged them before I gift wrapped them. They were the hit of the birthday party with the kids and the adults! Essential that you turn them on at the bottom of the device, place them in the palm of your hand, and them turn them on with the remote. Keeping the remote in your hand close by the device for quick turn off is helpful, too! It takes patience to learn the trick to using your hand to control the device, but oh so fun when you do! The battery is short, maybe 20 minutes, but charges quickly, less than 30 minutes at most. A fast, bright, colorful, fun gizmo for the entire family to enjoy! Plan on ordering more of these!! (If the wings snap off on crashes, you can pop them right back on!)Kids got these for Christmas. Lots of fun! They are lightweight, don't have to worry about them breaking anything. They don't hold a charge for a long period of time but a decent amount,plus they don't take that long to charge. We don't really use the remotes all that much, but they're there. If you need a little gift that isn't expensive and will give lots of movement and fun...get this!they seem like alot of fun if u have a large area to use them. We tried them inside the house and it went crazy..lol. they fly very high and very fast, that my kids kinda got scared. They liked them, but can't really control them to well yet.Very suitable for children’s entertainment. I bought this toy for my nephew, he and his sister in the room to play for a long time, he said it was fun, very like, see the smile on their faces. I think it is a great gift.I got these for my kids for Christmas expecting them to be a crowd pleaser for a day or two, until they broke. But, they haven’t broken yet. And, they are a kid pleaser. Of course, they do crash, and the parts are flimsy. But, so far, we’ve been able to snap the parts back on and keep flying them.this will be given as a christmas giftVery stylish, very soft, not broken. It is scientific, the packaging is in place, and it is simple, generous and practical. Very safe, the battery is small and safe. Not bad, very stylish, good dosage, and tasteless. The workmanship is quite good, the soft and hard is moderate, it can withstand playing without breaking, the sensitivity is very good, it is very suitable for children to play.Grandsons lived them! To me that matters more than anything!
