If you want performance, yes, it is worth it. If you want it to be quiet, NO, it is not even the lowest level ladder is heard. I don't know about wear and tear, it is expected to be tested. The assembly was easy, it has a remote control, although you can control it from your mobile phone if you have IR Remote Control on your phone, it is compatible with some other models on the list. If you are looking for quietness, then with a plastic propeller you will find better options. If you want performance, I recommend metal propellers.

The money of it is not worth it in any case 55 euros. It makes a lot of noise for home, it is for outdoor use, and again the propeller is 45 euros for outdoor and moreover it is metallic with corners, that's why it makes noise

The feeling as soon as you see it is that it is cheap and clumsy as a product, the photo deceives you.
