I have purchased several of Linda's Deluxe Hair Magic Combs. Have given many as gifts - everyone who see's them wants one. Those of us with thick hair love the large, deluxe type. They are strong and reliable - forget bad hair days or putting on the baseball cap - especially in the summer! I do not know Linda or anyone in her company but my friends and I rely on their Magic Combs! AND they have a "warranty"! Thank you, Linda. Charlene Eastman Washington, New Hampshire
