but I have ended up being really happy with this purchase
I was skeptical about this, but I have ended up being really happy with this purchase.  I have medium thick hair, with a little bit of curl/wave that tends to go every which way.  I didn't want to fully straighten my hair because I like having the volume.  This is a great product for me to tame down the parts that are a bit out of control, but maintain the volume.  If I wanted to fully straighten my hair, I think I could do it with this, but I haven't tried yet.  I am very happy with this brush.
