Terrible.
The brushes have a stabilizing attachment that has to be installed.  The plastic is brittle.  The attachment breaks or the brush breaks.  If the attachment breaks, the brush is flimsy and will not work to well.  If the brush breaks then hair will get caught and be pulled out.<br /><br />Not good, not even worth a star but Amazon made me choose one to write the review to save you money.
