I have the Olfa, Fiskars, and Elna rotating mats. They can't compare to the Martelli 16" big round one. I'm not a fan of Martelli products but do like the rotating mat. It will last me my lifetime. I think the Matilda's Own Rotary mat is very good from the reviews it has. I haven't used one of those. I see Matilda's 15" is on a sale at Craftsy now. $49, reg $75.
