Product review (1 stars): It will damage your hair
No good I thought I tried this model because u can interchange the brush, but the brush hardly  turns in low or med setting is like the turning machanisim is very bad  and it tangles the hair than it brakes off the hair it's horrible. If you wand to damage your hair than use it it's guaranteed. I had the other model the one with the fixed brush for 3 years it worked great than it stop rotating but I was very happy while it lasted. I wish I could find one like my old one I give it
