Bests & Worsts Reviews from Amazon

I installed the MX4 on my new 2018 Ford F150 yesterday. I did a lot of online research before selecting this tonneau cover. I ignored some of the negative comments on the MX4 as one offs, but unfortunately that was not the case. The side rails were heavily scratched even though the packaging was intact and the rails were in individual plastic bags that showed no wear. This is totally a quality control issue as rails are getting scratched in the manufacturing process and BAK allows them to be packaged and shipped. The top of one of the panels also has a long scratch on it as well. The overall design is good and the installation was also pretty easy. It hasn't rained yet so I can't comment on how well it seals the bed. I suspect not that well given that the rubber seal along the top buckles at every seam. Overall, I wish that I had heeded some of the negative comments on the MX4 and selected another manufacturer. Haven't decided whether I will return it or not. My advice would be to avoid BAK until they improve their quality control.
