"I have 2 children and I host Halloween with friends. I've bought these the past 2 years so each child had one. Parents and children were delighted with them. Out of 24 total, one did not work, one had trouble turning on & off but we got it. The price is so cheap, I think it's worth it for safety. I can't find these clip-on kind anywhere in the stores around me."
