Pros: Doesn't burn your hair or hands and heats quickly.
Cons: It makes a clicking noise that is a little annoying while steam is on
I found these curlers very easy to use. What is great is that it uses steam, so it doesn't burn your hair and you can touch the rollers. Also, they are very easy to put in your hair. The clips just snap right over the roller, instead of those pins that other rollers have. What I didn't like was that the kit mainly came with large rollers. I like the size of the medium rollers and I do have long hair. The large rollers were so big I didn't get much curl from them. The first time I did it, I don't think I let the rollers sit long enough on the steam because my curls fell right out, but the 2nd time I did it, they lasted all night. I would suggest leaving it on the steam at least 15 seconds. I have fine hair, and a minimum for me was 20 minutes to leave the rollers in. You definately could not sleep in them comfortable because with the clips on them are rather large in your hair. Also, when you turn the ionic steam on, it makes this loud clicking noise to let you know the steam is producing. It gets kinda annoying after a while, but worth it. Overall, I think they are a better hot roller than the electric ones due to the fact it doesn't damage or burn and very easy to use.
