Fit great, easy to install and great if you need to flip it up to utilize the entire truck box.

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.

Far lighter in weight than the previous model I had installed on my f150. Same quality but much easier to fold back to utilize the entire space in the bed. Easy to self install and the quality of product make this a great option for covering the bed of your pickup.

Great product! Easy to install. No water penetration in the truck bed. Looks like an original OEM part.

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.
