Product review (5 stars): Just what I've always wanted
I have been blowing out my shoulder length (fine but dense) hair with a round brush for 35 years.  I am only sorry it took me so long to find this styler!! I'm in good shape, but my arms still get tired using two different tools at the same time, plus blow dryers can be heavy! The Infinity Pro is light weight and allows me to dry and style my hair much faster and so much easier! The bristles are soft but grabby enough to lift hair at the roots for volume. I really like the two sizes of brush head (that easily switches between them). The rolling brush head even makes my hair SHINY...something I haven't had for at least ten years.  It took me about one minute to figure out how to work the spin direction. I do hope it lasts because I love it so much!
