I purchased this mat about 2 years ago. I have used it minimally, and it was always inside when not in use. First the stitching that holds the panels together began to separate, and recently the mat has begun to fall apart and is making white flakes everywhere. My $9 green outdoor carpet which I have had for 7 years and have taken on numerous trips holds up better than this piece of junk. I am going back to my cheap outdoor carpet. This carpet looks really nice and is nice to walk on, but is not durable and will not last, unless you don't mind coughing up the cash for a new mat every year.
