Do yourself a favor and throw the instructions away before you start assembly. They are basically useless and YouTube has some great instructional videos. Once I got that figured out, install was relatively easy with a second pair of hands.Cover snaps in easily and is flush with bed rails. It looks really slick. Access to the bed is easy and can be done from the side without climbing into the bed. The drain hoses are a nice touch and after testing out a 30 min drive in moderate rain, there was no noticeable water to be found. It's nice that the rail system can still be in tact after the install as wellThe buckles that you use to strap in the cover panels when it's folded are not high quality. They are a bit of a redundancy anyways , but still a little better quality expected on something this pricey.The tailgate needs a seal as I'm sure at some point some moisture/dirt will find its way in there.Overall - good but not perfect. 4 stars for me
