I love my hoop from hoops of creation. I have a similar defect that I think Christy pointed out, which is it shorts out. The battery life is also short, but I'm starting to think it's because there is some wiring problems. Also, thinner tubing = less battery life. I haven't figured out how to open mine, a friend of mine opened hers (also wiring issues) because she didn't want to have to wait to send it to them and then get it sent back...it works now, but she was unable to put it back together in a perfect circle....as for mine, the cooler colors turn off earlier than the warmer. Also, it was glued improperly so when I do breaks, the circuits get pushed around in the hoop, and I have to end up pulling the whole string of circuits back up to the opening where the switch should be chilling under...it's silly.
I got my hoop when they were kinda starting off, so maybe they have gotten better. I've seen some of the hoops that they are busting out now for people, and they look amaziiiing. I didn't go to them to get my second LED, which are a pair of meteor minis from cosmichooper. I'm still deciding whether I should go back to them...I'm thinking if I do, i'll let them know about my previous hoop problems from them.
Some people have given rave reviews, so perhaps, like I said, they were starting off and maybe now they have gotten better. I would keep asking....they do have amazing color options and strobe options, which I like. But get the thicker tubing, as the thinner provides shorter battery life and perhaps less durability.
