This is a very poorly designed product, especially considering it is far more expensive than most sets I have bought before. The clips that hold the curlers in place are huge, there is no where convenient to put them like the small metal ones. They are heavy and feel clumsy on my head. There is no where nice to grab the curlers so I burn my fingers sometimes. I guess it heats up fine, but they are so difficult to deal with that I have yet to get a nice curl.
