What is the name of the ceramic hair straightener that also curls?

I heard those don't work very well. You can curl slightly with a flat iron. Otherwise I'd use a regular curling iron if you want major curls.What is the name of the ceramic hair straightener that also curls?

Any hair straightener can curl your hair if you know how to do it. The one you are thinking of might be the GHD. They are $300. I bought mine from Big W for $40, it heats up to 250 degrees, I've had it for 2 years, and it curls my hair.
