My hair is thick, coarse, and heavy. I find that my hair holds a curl best if I use a flat iron, however, an iron or curling wand tends to give me very defined curls that look kind of poofy, whereas I wanted to get something that can give me soft waves which is pretty tough with stick straight hair. My hair is usually either straight, or super curly. After doing a full day of research on hot rollers and steam rollers, I decided to go with this Caruso set. The packaging looks like it came straight out of the 80's/90's, but sometimes, the best products are those that have been around for years, right? This set comes with 30 rollers, 6 of each size - I wish you could choose the combo of rollers you want since only want the jumbo and large ones and would likely never use the medium, small or petite ones on myself. The unit puts out steam very quickly. After plugging in the unit, I brush out my hair, take out the first roller and remove the clip, pull out the first section of hair and the steam is already coming out. There is definitely a learning curve to using this. The first few times, my hair lost the curls very quickly even after leaving the rollers in for ~1 hour. The next couple times, I took out the rollers and I looked like a mad woman. I brushed out the curls with a boar brush and was left with a horrible hair style that I was tempted to wear in a pony tail. Finally, on my last attempt prior to giving up completely,I tried taking the first roller out shortly after putting in the last one, and I got crazy curls that settled down to waves after 10-15 minutes. I normally don't need a lot of product to hold curls if I use my flat iron, but with the Caruso unit I definitely need hairspray after. Even thoughout the day, my waves were getting looser and looser, something I'm not used to when curling with my flat iron. HOWEVER, for days when I want some texture and volume in my super boring straight hair, this does the trick. So, while not a replacement for my curling wands and certainly not my flat iron, this Caruso steam hair setter does have its own purpose. I was hoping this would save me time, but it still takes me a total of ~30 minutes to put in the rollers and take them out, whereas using an iron would only take me 20 minutes. Perhaps I will get better with practice. Overall, I think this is a good product. Really-anything that can curl my hair, I'd consider good. I think the clips can improve; sometimes one of the corners catch on improperly and the whole thing becomes stuck, meaning I have to take it out and try again. As well, I'm not a fan that the foam on the rollers degrade over time and replacement rollers seem very $$$ - since I would probably use once or twice a week, I think it'll still last me years but not really looking forward to the day I have to spend $20+ to replace 6 rollers!
