It's COMPLETELY worth it, I had a curling iron and it left dents in my hair and it also limits your styles. I then bought a karmin g3 clipless curling iron and it was much faster to curl and they lasted longer too. It takes a bit of getting used to and I used the beginners heat-proof glove for the first couple of times...but after you know how it's done it's way faster and easier than a clip curling iron.

I got the karmin one because of the heating and the tourmaline ceramic barrel, which apparently is faster and safer for hair.
