For the new B-model (since 11/2014), these mats are no restrictions in the area of bad weather absolutely recommended. All four parts, especially in the driver's footwell in its supply pressure fixtures, match exactly. The other three mats, also front right are normally designed without attachment, in which all parts are even now, after several weeks of use, be described as absolutely non-slip due to their respective ground conditions. Odors I could not determine from the outset, although I'm not unsensitive, more sensitive in this regard. Adjusting, inserting and attaching (on the driver's side) should not be a problem even for rather not gifted artisan. A very strong buy recommendation in comparison to other products contemplated.
