I bought this because a buddy of mine recommended it. I was very surprised at how fast it arrived and how easy it was to install. Took me less than 10 minutes. Just align it, tighten the two front knobs but not too tightly or you'll crush the foam strip & latch the two back spring-loaded clamps and that's it!! Remember to lock the tail gate for added security although a quick slice with a knife to the tonneau and you're in. Just as quick to remove if you want to load a four-wheeler as I have.
