Works fast!
This brush is easy to use, I don't have much hair, but it is stubborn.  I have been using a flat iron for many years and I love how it makes my hair look but it takes forever to get it the way I like it.  When I started using this brush, I started with 300 degrees but it was not doing the job, I increased temp to 400 and that did the trick.  I do use a serum like CHI or Biosilk to finish, it definitely cut my straightening time quite a bit.  It takes me less than 10min to get it nice and straight.  Downfall is that it did not come with a thermal pouch, so I have to leave it out to cool off, so when I go to work it sits out until I return from the office.
