I have very straight and hard to curl hair. Through the years, I've bought and returned so many hair curlers as they just could not do the job, or they could but the curls fell out quite quickly. I kept this one, and ironically, this curler is the cheapest among them all. It heats up fast, and easy to use. No, it does not have those fancy features, or gold glided barrel, but who cares, it really does what it supposed to do, curling hair. My curl will last about 12 hours, till 18 hours there are still waves, past 24 hours you can still tell there's something done to the hair. On top of all good things about this curler, it's a dual voltage! Isn't that great, especially when I am travelling abroad. For $12 plus change, it definitely worth it.
