The item is as described and delivered on time. As described in the reviews, the mats fit into the Holder studs and make a stable impression. Since I had the mats are half a day on the balcony until the exhalations partially described were not noticing. I doubt that it besides the smell of nunmal new products adhering to this basic material, would ever give an intense smell of rubber. We are therefore satisfied with this product and would buy or recommend again.
