I purchased these for my 2009 Mini Cooper. All in all, I was generally dissatisfied with them - especially considering the expense.
The idea is great, but the product is made of much to stiff a material. The fit was in no way "perfect" and eventually too inconvenient to keep in the car. Tried using Velcro to keep them near the sides, but became too much of a pain.
I believe the idea is a good one, and perhaps if they were made of a more supple rubber-like material they might actually work as claimed. It would seem I must have at least 100 words in order to submit a review so I've added a few here to "qualify."
Product or Service Mentioned: Weathertech Auto Floor Mat.
Reason of review: simply don't perfoem well..
