Serves its purpose. We previously had a similar rubber doormat that also had some type of natural fiber that we kept at the entrance to our sliding back door.  Unfortunately due to the fact that the area is uncovered, the natural fibers would get soggy during rain and never dry off properly.  This was an excellent alternative since it is solely rubber and can just be hosed off.  But you will need a runner or another mat on the inside to catch any wetness or moisture on shoes from outside.
