Quality cover that's worth the money
The packaging is well thought out and it arrived undamaged even though the box had corner damage. Installation took about 90 minutes. It's a very clean look, latches easily, and works as expected. I had to adjust it once to keep it from leaking around the top of the tailgate. The margin of error between sealing the top of the tailgate and keeping the tailgate from opening automatically is slim. I would buy it again. It's worth the money.

Absolutely worth it! Easy install.
Upgraded from the factory Ford trifold. This top is perfect. Fits excellent. Automatic tailgate opens and closes as it should with no interference. Had a major storm yesterday and the box was completely dry except for some water on the tail gate, which I expected. There is a small clearance at the tailgate to allow for the automatic tailgate release. You could adjust it closer if you need. I'm very satisfied. Looks so much better too.

Nice Cover
Quick delivery, well packaged, no missing parts. Easy install. Looks great. Was deciding between the X4s and the M4 but I like that the M4 can be partially open. The X4s is either fully closed or fully opened. Very satisfied.

Solid product
i had another brand it was a roll up but the faux leather came unglued and the aluminum slates were coming loose. I tried this style this time around. Install was a breeze! it seems durable and i have already had to make a run to the dump and had the bakflip fully up and had the full bed length full of yard trimmings. so far no issues.
