Curling wand - 1 inch barrel.

Pro: It's freaking hot and good for certain hairstyles.
They give you this heat resistant glove for your free hand but I honestly don't think it works.

Con: It's SUPER HOT! It only has one setting, and once the cord slipped and I grabbed on to the iron by the barrel for 3 seconds and it was the most painful, ice pack strapped to my hand days of my life. Honestly since then, I've never used it again.

Cost :$25 - $100 - depending on brand, where you get and if you got a knock off or not.

I still prefer Hot Tools gold professional Marcel iron to this product.
