Review on 🚪 Durable Rubber Door Mat - Non Slip Welcome Doormat, Indoor Outdoor Rug - Low-Profile Entrance Large Door Mat for Entryway, Garage, Patio - Heavy Duty & Easy to Clean - 36 x 60 inches, Gray by Jerry Crist

This is a really nice rug. It's heavy and stays in place well. No twisting around the edges or constant movement on the floor. I put it behind our sliding glass door to the backyard and it's perfect for kids who need to clean their shoe soles a bit before going in. Great at catching and hiding dirt - I was shocked to see how much dirt was hidden in there the last time I met him. It's very rough and uncomfortable to walk barefoot, so personally I wouldn't recommend it for indoor use. Can't comment on the smell as I've never used it internally.
