I purchased a Bakflip MX4 in September 2023 and have been overall pleased with the cover. Today I had to glue a rubber piece back in place. Also, a bracket came out of the edge causing a hump in the cover. That's minor but so far no major malfunctions.

This is a phenomenal product. The quality, security, fit, latching mechanism, weather seal, and the ease of removal, beat my expectations. The downside to this particular model are he metal arms that help hold the cover up when folded up. They do not fit in the hooks they are meant to sit in, so the arms swing around in the bed of the truck, or fall down and get in the way of things. That and the quality of the foam paddings could be enhanced. Otherwise this is a fantastic truck bed cover.

Works as expected. A little water comes through when there’s a heavy rain. Not really an issue so far. Just keep things in the middle and away from the tailgate. Install was a little tricky at first, but a YouTube video showed me the trick.

This was an easy install and works well. It is not watertight. You do get some water, but very little. I would buy again if ever needed to.

This is a great tonneau! I had a soft cover in the past and it was okay, but this is far and away the best choice i could have made.

I am now 3 years in. Still love this purchase. I drive mine through a car wash weekly if not more. Still solid. Nothing has worn out. Solid product. I’m only here to promote them since I don’t need a new one. Thanks for a great product.

The Bak Revolver X4s is a fantastic tonneau cover. It's incredibly durable, easy to use, and looks great on my truck. I was pleasantly surprised by how quickly I was able to install it myself  the entire process took only about an hour and a half. I highly recommend this cover to anyone looking for a top-quality option.

This is the 2nd Bak Flip I have owned. The first I had professionally installed. This one I did myself. It was simple and gives my truck a huge “trunk”. I highly recommend.
