Bought like 20 of these $1.80/ea suckers for Christmas so everyone can have one to send off. Apparently it's a chore and plenty of entertainment just getting one of them up. Some went off smoothly into the sky but some others barely made it over nearby trees and a couple failed to gain hardly any altitude and we had to chase them down in the golf cart in fear of them setting a neighbors house on fire. Ordered more for New Years. Merry Christmas
