Unfortunately these curlers didn't work at ALL for me. I have very long, very thick hair, and was excited to order a product I thought would not only offer styling versatility, but add volume at the root as well.
I can't even get the curlers to stay in my hair! And believe me I've tried. If you're like me with very long, thick hair, order this product with caution - you may just be blowing your money away. The only way these curlers remotely stay in my hair is if I pin them, but the main reason I bought them is because they're supposed to stay in naturally. And of course, once removed, my hair is not curled in the least. No extra volume at the root, either.
The brush is definitely decent, and my favorite part of the kit. Not worth $30 though.
If you have fine, thin hair you just may be pleased with the product. But from my experience, I feel the product offers nothing but false promises. I am very dissatisfied.
