We ordered 1 red and 2 blue drones. Two for our 8 year old nephews and one for my 80 year old husband! Revain sent 1 red and 2 black drones but they all worked great so my husband told me to order 2 more blue ones. The blue ones are beautiful. We are planning to give our nephew a red one and a blue one plus 2 black ones as spares. Now my husband has asked me to order 2 more blue and 1 red and 1 black so he has extras. All 5 we have received so far work perfectly and are a lot of fun to watch fly. The only problem is an almost invisible switch and charging port. My husband painted the switch and port a contrasting color around the port so they can be seen.
