Ok, but never heated as well as advertised
I've been using this brush for over a year and have been reasonably happy, though it definitely doesn't do as good a job as a flat iron, but is a lot faster on my thick, wavy hair, even after chemical straightening.  I do have a few issues with it, though:  first, it states on the box that it heats to 450 degrees, but since I first turned it on, it has not been able to register any higher than 230.  Since it did an ok job, I kept it anyway, and thought maybe I would just get less damage with less intense heat.  But maybe that accounts for the less than stellar performance?  Also, I have noted quite a bit of breakage in my hair, especially in the front where I use it close to the scalp.  I have multiple scars on my neck from inadvertent burns;  I think the heavy weight and somewhat exposed heated areas and the motion required to straighten my hair underneath probably contribute to this phenomenon.  Overall an ok product, but I probably won't buy this particular brand/model again.
