Excellent product! I would’ve ordered the MX4 but I wanted gloss black instead of matte. Gave 4 stars because have to shut tailgate first before securing last panel of cover (not so on MX4).

The installation was pretty easy. I found the videos online were better than the actual paper instructions that were provided. The product seems to fit fine and works great. The only issue I had was with some rubber weather stripping pieces that came unglued during shipping or packaging. I was able to realign them before install and it seems to be OK. Other than that, it works well and looks good.
