When I first saw this I was really excited. I could not wait to use it as I roll my hair in curlers a lot. I get so tired of sleeping on hard rollers in my hair. So when I used this I thought that I could roll my hair in the morning and have my hair done and just a short time . Unfortunately, that was not the case. When I attached this product to my blow dryer and put the cap on my head over my hair and turned on the blow dryer it filled with hot air and popped right off of my head. I replaced it onto my head and secured it just like it said too and turned it on once again only to have it fill with hot air and pop right off my head again. After several attempts to dry my wet curled up hair with this device I finally gave up and just took the rollers out and dried my hair with just my blow dryer. I'm very disappointed in this product. But, if you'd like to give it a try and see if you can get it to work by all means give it a try.
