I have long, pin straight hair that does NOT hold a curl.
I have used every possible curling iron, wand, hair straighter to try and get decent curls in my hair that hold for longer than 10 minutes.
This is the only one that works. It's easy to use, and for some reason holds the curl forever. I even brush out my hair after and rarely use hair spray, and still the curl holds. Its unbelievable, I cant believe that something so affordable is the only thing that works with my hair.
I'm going to buy the next size up so I can do bigger waves.
The only downfall is that because it actually gets my hair to hold a curl, if you make a mistake or crease your hair, it shows. You need to wet that piece, dry it and start all over.
