I have a Nume with interchangeable wands, and I love it. I don't use it often, but when I do, I have great results. I think it is just on/off. I don't recall a temp setting, but my hair is fine, so I only leave it wrapped around the wand for 3-5 seconds, anyway. Search the net for discounts. They are out there, and there are some good ones. Lots of YouTube tutorials, too. HTH!
