Flat iron addict
This brush works, just not as well as a flat iron.  I have thick / coarse hair and I have flat ironed for years.  My objective for ironing is to straighten my hair and seal the cuticle to reduce frizz.  I used the brush on max heat  (450F) and still didn't feel like it was hot enough (I only use 395F on my flat iron).  Picture shows my hair after blow drying, after using the brush (sectioned my hair and followed the instructions to get best results), and after my flat iron.  The brush did reduce my hair puffiness but not enough, and it didn't seal the cuticle at all.  I will be returning the brush as it didn't produce the desired affect.
