Query: Not for thick hair

This straightener has no heat (I've touched it while hot) and does not work at all for thick hair. The crimper did nothing and the plate that was supposed to make waves simply made me look like I could be the bride of Frankenstein. YIKES! The other plate did absolutely nothing for my hair. I gave it two stars because it might work better for finer hair.
