UPDATE: This cover has gone through a bitter cold and wet Midwest winter with no problems, rips or leaks. We are very happy with the purchase and the price. I updated to 5 from 4 stars because of this.
Nice tonneau for the price. Took the hubby 15 minutes to install. It is a strange fabric material. Cannot yet speak to leaks as the weather has been nice. The foam insulation touches the rails of the truck all we don't expect issues.
