Review on New Star Restaurant Grease Resistant by Dipp Samrock

I bought 4 of these mats to make room for dishes in my restaurant. They lasted about a week. The floors there can be wet so we bought them to keep our kids from slipping. After about a week, the corners started curling to the point where we couldn't even use them anymore. We tried turning them around but they were too far away. Curled up tight, now they don't lie down. Loaded for several days. The edges were still curled. There's nothing good about tripping on a mat!
