The rubber tub is ne very good thing and is intended to protect the trunk floor against dirt. The size is appropriate even if it is not fit 100%. The knobs are good and help that things do not slip back and forth. So far so good, but the chemistry is it unsustainable. Even after several weeks of airing in the fresh air (not in the car) the smell has not decreased. Only after a few months !!!! I think it is harmful to health, not make out what drinstecken of plasticizers and chemicals which. I would not buy it again and do not recommend it!
