I do really like this.  I have very fine very curly hair that tends to frizz badly when I straighten it.  Not only does this cut down on the amount of time it takes to straighten (significantly) but my hair isn't frizzy.  I do agree with others that this will not get hair stick straight but it does exactly what I want which is straight but with volume still.  Basically I just put my normal product on my wet hair, blow it mostly dry using my fingers then do the rest with the straightener brush.  Take about 5 minutes total!
