Product review (2 stars): Don't waste your money like I did
I have long, naturally straight/wavy hair that's on the thinner side of average.  I could only get this to work on dry hair and it left my hair looking and feeling like I had a salon quality blowout for about 5 minutes, then it went flat and wavy (and not a good kind of wavy).  I've tried it multiple times and I always get the same result - it takes forever and doesn't last.  My hair looks more volumized when I spend 5 minutes straightening it.
