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.

After searching online I found the best price with free shipping here. Fast shipping and easy installation of my product.

Very good service, product arrived promptly.

Recieved item in great shape. Could be a little faster with shipping, but over all, I had a good pleasant experience. Thank you.

My shopping experience is top notch. You actually had the brand I really wanted. the only real issue is shipping, didn't get a tracking number like promised items just showed up.
