Bests & Worsts Reviews from Amazon

When I received this mat, it had a very strong odor so I posted here asking for feedback and the company posted a respond on how to clean the mat to eliminate the odor within an hour of my posting. I responded to them, before I use vinegar on the mat I wanted to ensure if in fact the odor doesn't clear from what they offered that I could still return it or would it void my return. NO response. I've now posted that question three times in a few days (amazon won't post a question without a response) and the company won't respond. I am left to assume that while they encourage you to clean it with vinegar once you do, it voids a return so you are left with a smelly mat. I'm returning it before I try cleaning it based on the other reviews here that the smell doesn't in fact go away.
