auto rotating curling iron

Can someone recommend an auto rotating curling iron that they love? I have a wand but don't really like it-I'm always burning my fingers.

I just bought a kiss instawave. I have naturally curly baby fine hair that I blow dry and flat iron. I don't like my natural curls because they are too frizzy and shapeless. (Think Elaine from Seinfeld). Kiss just twirls the hair around the barrel rather than suck it up into a chamber. Honestly I didn't think it would work on me. When I normally use a curling iron the curls disappear within ten minutes and never look right. This machine gave me big bouncy curls that lasted all day and became waves the next morning. It is too time consuming to do my whole head every day so I usually just do a few face framing waves. I really wish I discovered this years ago.
