Don't give up on this thing when you open it up and find that it doesn't fit your hair drier. It does. Make sure you put enough pressure on it to lock it onto the end of your hair drier, it does take some serious pushing the first time you use it. After that, it comes on and off very easily!
Once you have it attached correctly, it works great. I have wavy hair and it is a great way to get beachy waves in a hurry.
