The floor mats I purchased for my car work like a dream.  They were just as described in the listing. The shipping was also pretty quick. I just wish the price was about $20 cheaper. Other than that I was completely satisfied.

sounds too inexpensive, but hey you only live once...
After searching online I found the best price with free shipping here. Fast shipping and easy installation of my product.
