Worked great, very happy with it.
My hair is fine but thick (lots of it).  I've decided to grow it long again, but wouldn't wear it down very often because it sort of poofed with humidity here in north Florida or looked dry and poofed in the winter. I didn't want to use a flat iron because I would always cause a kink at the top of my head and I didn't do a great job with getting to the back of my head.  So looking at options I found a couple of just straightener brushes.  This one was rated good enough and the best price for it's rating. I have used it only once so far and I really liked it. Take a section of hair, brush it - then another section.. no kinks, went through hair twice and you would have thought my hairdresser straightened it. Worked perfectly. I did talk with my hairdresser friend and told her about it and that it gets nice and hot.  She advised hot is good and not to go over and over it, that any iron will break down the hair if going over and over it with a straightener. I worked through my hair 1x on high setting from the top and another from underneath and I thought it did a great job.
