Product review (4 stars): That the brush worked perfectly and was easy to use.
At first I had to master the buttons which I did quickly.  I found no problem with using this and actually loved it. until my hair started coming out in patches. It didn't even occur to me that it could be my new styling brush, but this morning I used it and the brush was full of hair.  I will not use it again until I make sure that it is not pulling my hair out.  I am not saying that the brush pulled my hair out...just want to make that clear.  But until I know different...I'm giving it a rest.
