I couldn't get past the smell...a very strong, noxious, chemical smell. The mats sat for several days but the stink lingered, so I packed them back up and sent them back. I bought aInterdesign 60663 Pebblz Sink Matin the past, and had to throw that out as well due to chemical smell that never went away. I had hoped that maybe that was just a rotten batch that was made in China, because even though there were numerous reviews similar to mine about the smell, the more recent reviews included comments that theirs didn't have any smell. I thought I'd give Interdesign one more try. That's the last one, though. They still make a toxic smelling product.
