About BAK BAKFlip MX4 Hard Folding Truck Bed Tonneau Cover
77% praised the durability, but 23% experienced wear and tear
After using it for almost three months, I found no problems with the product. It is easy to open and close and looks great. However, it is not entirely waterproof due to its low profile.
The tarp with sun heat melts the glue and causes it to move, which can lead to the setup system not locking in the right interlock channel system and bending the metal. This can worsen over time and render it unusable after 3 years.
There are unacceptable gaps in the components and the support seems to be fine with it.
I have sent an email with a breakdown of the issues related to the durability of the truck-tonneau-covers.

84% found it easy to install
Installing the truck-tonneau-cover was easy.
I found the product easy to install and nice.
The installation was easy with no noise or flapping. The build quality is solid and it operates reliably.
76% appreciated the security features, yet 24% didn't
I chose a solid cover for added security to the gear in the bed, as I have had soft covers on other trucks.
Approximately 8 inches from the front of this Tonneau cover and on the left side of this Tonneau cover does not lock into the rail.
79% were impressed with the sleek design, but 21% weren't
I am satisfied with the design of the tonneau cover. It is low profile and easy to install, which makes my truck look good.
I enjoy the truck-tonneau-cover but wish it had attachments for bike mounts or kayak mounts.
I noticed that the rails on each side were bent on the ends. At first, I thought it was by design but upon closer look, I realized it was not by design and didn't fit. Rephrased: The rails on each side were bent on the ends. At first, I thought it was by design but upon closer look, I realized it was not and didn't fit.
I found the truck tonneau cover to be of poor quality and the company's customer service was bad.
76% liked the tight weather seal, but 24% experienced leaks
The cover fits nicely and seems weather tight, but I haven't tested it in the rain yet.
The tonneau cover leaks water and the metal frame slices into the side seam material, which destroys the side seam seal in just a few uses.
90% appreciated the weight capacity, but 10% experienced issues
I have a damaged cover that weighs 70 pounds and I have to take it to the dump and pay $50 to get rid of it.
