I purchased this product and upon the first time using it, the attachment came off. It is poorly designed (the button to remove attachments is where you put your hand to hold the thing) and cheaply made (feels as though it is about to fall apart ). The heat doesn't come out of the holes on the roller, instead the heat comes from the main unit. I used it one time and gave it away. I later purchased a better brand where the heat comes through the holes on the roller as it's supposed to! I would not recommend this product.
