Calily works well.
The Calily heated brush smooths my hair very well and is much easier to use than a a straighten iron.  I think it's because a "brush" feels more natural to use.  My only constructive critisism would be for hair care heated products in general:  to change the location of  the power buttons.  They are usually placed on the handle and I inadvertently shut the power off because of the location.
