I have really liked their typical front and second row digital fit mats, and the new version "Floorliner HP" does have knobs on the bottom to help hold them in place, and they do feel a bit thicker and more robust then the original liners in my GX470 and Honda Fit. I am sure some of us have higher standards, or a lower threshold for the performance of certain items, but sometimes I really question what certain companies were thinking when designing products. Like the weathertech cargo mat. The bottom was almost perfectly smooth, and there really isn't anything that would hold it in place. Then the whole 3rd row use issue, it's like WTF! Your product testers should be a family of 5 with dogs and an active life. Not desk jockey's who never even use the 3rd row or haul damaging cargo.
