The ExactMat we purchased for our oval shaped dining room table fit perfectly. We were amazed. It looked like glass, at first. My only question is what is the max temp that this ExactMat will take without leaving a mark. My husband put his coffee cup on it and I can now see the round spot on the ExactMat where he put the cup. I also have a spot where I sit that was left there after I heated something up on a plate in the microwave and put it on the ExactMat. That is the only reason I did not give a 5 star rating. I thought it was a tougher material than that. Is there any way to remove these blemishes from the ExactMat? I look forward to hearing your response. Since my initial review, Katie in CSD has been working with me to help resolve the issue. I have changed my rating from 4* to 5* because of her outstanding resolve to make sure I was satisfied with our final resolution. My only advice would be to make sure and put a pot holder down before putting anything hot on a crystal mat finish. If you prefer not to do this, then you should purchase the Riverston e finish instead.
