I wanted to like this brush. There are a couple of things that I don't particularly like. While there is a swivel cord it does not work well. The cord has a tendency to wrap around the brush handle. It also doesn't get hot enough to create the wave that I've seen in their videos. There is a learning curve. I have been able to get some nice curls and waves bit since the unit doesn't get hot enough they fall out within an hour or less. When I style my hair with a curling iron the curls and waves stay all day. I will probably gift this to someone who might try it for hair straightening. I wish I had not spent the money on this tool. Back to my curling iron.
