Review (5/5): holy crap.
I bought one of these from Groupon Goods, and I love it. I have long, straight hair that is impossible to curl -- well, scratch that, it curls, but in about an hour it looks straight again. This thing, though...after about 5 minutes of twisting and curling, my hair looks awesome. It looks like I had it French braided for a day, and then unwound the braids. I LOVE it. It makes sweet, romantic curls and waves, and the best part -- it lasts for HOURS. The first time I tried this, I curled my hair at 12 p.m. and it was still curly at 8 p.m. Hell yeah!
