I just love my Xyron, use it for most of my layouts. Sometimes repacement mats and blades are hard to find. You can always find them on SB.com
I was so excited to get the new replacement mats because SURELY that must have been the reason why my xyron cutter wasn't sticky and all the paper was getting wasted. But sadly, I put in the new mat and I'm still having the same problem. I think I'm going to have to take the loss and sell it.
I like my personal cutting system BUT these mats don't last at all like Xyron says. There is also a problem with them "sticking" down and holding onto the paper to be cut.
