My 2012 Toyota Tundra has mat anchors on the driver's side, but not on the passenger side. I purchased some new molded floor mats, and the passenger one slid all over the place when my wife would get in and out of the truck. I decided to try Eagle Klaw. They were very easy to install, and the floor mat is nicely anchored now: no more slipping and sliding. They really worked as advertised, and I thought the price was reasonable for such a well-engineered product. Shipping was fast, too.
