Sturdy, solid product!
Bought this for my husband’s 2019 Chevy Silverado. He loves it still, 4 years later! Fit perfectly, easy to install, very functional, secure, water proof. Definitely worth it!

CarbonPro Buyers BEWARE!
I'm sure that for a standard metal bed the cover is fine, but on a CarbonPro bed I'd wait until a different manufacturer comes out with something better. Installation process is awful, it involves drilling holes and aligning a metal clip to do so. The clip is a real pain to get aligned correctly. And you have to do this 10 times. There is not a clip anywhere near the very rear of the cover so it increases the gap over the lift gate even more. The fit and finish is awful. There are gaps in the components that I believe are unacceptable, their support however feels they're just fine and within spec. Their support is marginal at best. They'll try to get you to do a bunch of legwork to try to compensate for the fact the cover is too small, leaks to the point of wondering if you even have a cover on the bed. The strap attachment points when you flip up the cover leave dents in the cover, I'm sure their support also thinks that this is perfectly fine (I haven't contacted them about this). Their support is generally fine with taking your money, providing a mediocre product and implying that you installed it wrong. I unfortunately will end up keeping it though as there aren't any better options.

SWEEEET!
Easy to install, took me well under an hour. Good quality, really sturdy with some very nice features. One of my favorites which makes this hard folding cover stand out is that it folds up to an upright position parallel with the rear cab window and comes with braces on both sides to hold it there. This allows you to utilize the entire bed of the truck when needed. A lot of the other versions of this type I saw didn't have this so when you folded it back you would lose the functionality of about a foot or so of bed space. You get a truck for when you have to move things, you don't want to fool around with limiting your available capacity when you need it most. This is easy to install, easy to use, improves the security for items in the bed of your truck and allows you to retain the use of more of your bed space when needed. I would definitely buy this again.

Not bad, install sucked.
The cover does look very nice. Took me a few hours to install mainly because the manual isn't that great. Would be nice if you had a video for this specific one to install on the carbon fiber beds. I'm sure I could've installed in half the time without having to read the terrible manual on my phone. My biggest issue is the latches don't latch when I drop or even slam the cover. I have to kind of pinch the cover and the rail together so it'll latch. I don't see any way to adjust for this.

Terrible directions for install.
Great products but directions are horrible. I’m sorry but paying over 1k, there should be good directions to install. Instead, I got a QR code that didn’t have how to install in my application.

Best looking bed cover out there
This cover folds completely up to the window giving you almost the entire bed space. It is great quality and looks awesome on my truck.

Not worth the money
Quality appears good. It fit well. However there were no instructions, and the videos that they have posted are worthless. It doesn't mention half the parts. Was also missing a screw, and the masking tape that they used to cover some pre-drilled holes left permanent marks on the cover on both sides. Also had a big scratch, but it's on the underside. And it costs over $150 to return this item so I kept it. Definitely would not buy it again.

It delivered so quick, I waited just a couple days. It is my secon time use it, the Bakflip is pretty good quality product and easy to install so I ordered it again. But it is a little more expensive than other brands. That is why gave 4 stars
