Bought this to teach myself how to fly a drone next summer. Although the drone looks like a toy, it is a very sophisticated indoor aircraft. It is more suitable for grandchildren than grandfathers. First Complaint; The booklet is written in a script that is almost impossible to read without a scanning electron microscope. Second; Charging pins are hard to find. Somewhere it is mentioned that he is in the back of the ship. Finding out that the white lights were on the front, I found the charging pins easy. I'm not sure how long they will last. Third; It flies like a charm, except I don't know which controller button does what, and the drone spends most of its airtime completely out of control, bouncing off walls and crashing. This will be a great toy to drive the cats crazy once I get the hang of it. Grandpa still has a lot to learn.
