I bought two. fun af Until your nephew accidentally flies under the table/couch/whatever by himself. Run it through hair and balls of dust under even the cleanest of houses, and you're done. Not really a complaint. only reality. Imagine a vacuum cleaner and a cotton candy machine. They give you extra parts, but the chances that you'll take the thing apart, replace some parts, and put it all back together working are just a little more than zero. Think of them as disposable items. Not fragile, but not elastic either. Fun. A good student. But if you're already flying drones, don't worry. Contrary to many things today when it comes to drones, spend more, get more. I don't regret buying them but I think they are a waste of money.
