"I purchased this item because i knew it was going to brighten up the party and we blew them up w the helium and within 15 minutes they popped on their own. When the first one popped i thought it was because i put too much helium but then the others started popping by them selfs. I was very very upset and will never buy them again. So in reality i bought them for nothing. Because i didnt even get to show them off at the party."
