This is a really inventive product. No seriously. I use it all the time. It's thin and made of plastic (so it's not a solid device at all). But it serves as a wonderful hair lightener! I bought 2 and I love how direct the light is. The Velcro on the elastic band makes it impossible to fall off. I think they cost about ten dollars. Excellent purchase. I have ordered several items from Fotodiox, their products are reliable.
