I love this electric beard straightner comb! It doesn't overheat my husbands hair and it works really great! His scraggly beard that was driving both of us nuts, is not nice and neat and looks ready for the GQ! It comes with beard growth oil also. This heats up fast, has a rotating cord so I he doesn't have to keep turning the cord around or getting tangled up in it. it works easy and is great quality! This really does a fantastic job!
