This ceramic curling iron, hair straightener, and crimper is a fast to heat up and works great on all three modes. Simply plug in the tourmaline ceramic iron and wait a few minutes, there is a simple switch that converts it from a strightener to a crimper. Super easy to use, easy to get started and even easier to put away. We were very impressed that it was so easy to switch over from one to the other. The curler part is on the outside so that part is easy as well. We really like this three in one, much better than having to have three deivces all over your bathroom.
