Thanks for your comment. I think we all have different criteria for a 'good' product based on our own personal needs. I recently bought another dritz cutter with a small ruler and 2 extra 45mm blades because it was cheaper than buying a two pack of 45mm blades. I don't need the cutter or the ruler, but 3 blades - what a deal!
My spinning cutting mat gets an occasional spin, but, like you, my big mat and cutting table get the most use.
