Review title is If You Already Own a Hair Iron, You Don't Want This Brush. [SEP] I am a sucker for any product that claims to straighten hair.  Against my better judgment, I ordered this product, and sure enough, it doesn't work well.  The metal base heats up quick, but the way the brush is designed, it can't get at the roots of the hair.  So the first 2-3&#34; of the hair shaft remains pouffy while the rest of the hair gets more or less straight.  A hair iron works much more efficiently.  Learn from my mistake, and save your money.  You don't need this product.
