Great quality and looks!
Got the Ultra Flex cover for our 2019 GMC AT4 Sierra about a month ago. So far we are happy with it, we previously had a soft tri- fold tonneau cover on our previous truck and it was ok but started cracking on the folds so decided this time to upgrade to a hard version. We like the quality and love the looks of this cover. it’s easy to install, only needed help placing it on the truck because it’s a little more weight than a guy in his seventies with a bad back wanted to lift but everything else went well and was not a problem . It costs more than the soft version but If you plan on keeping your truck for awhile it’s worth the money. I’m not a expert but would recommend this product to anyone looking for a hard tri- fold cover

Great product, quick shipping, easy to install
Love the look, ease of use is great, durable and easy to install. The product was easy to install if you read the instructions and have some mechanical abilities. It was pretty easy to figure out. The cover looks great and worked as it was described. I love the look and the carpeted underside for ease of using it as a bench when opened.

Great cover!
This is what I expected. Much better than the standard cover. Easy installation. No leaks! I highly recommend this upgraded cover.

Spend the money!
Shipping was frustrating. Was given a tracking number and told FedEx was handling the shipping. Come to find out tracking number wasnt for FedEx but for GLS instead. Well GLS evidently sold the frieght to another company. Was delayed 2 times because my “business was closed”. People, it was shipped to my home. I work for a global shipping company and i saw through to BS. Psh...Pathetic. As far as the product itself. It is top notch. Spend the extra money for the Armor Flex with the bedliner texture on it. Easy to install. Took me 20 min.

Great Tonneau Cover
The Undercover Flex was a very easy install. I recommend having someone assist you while doing so. That being said, it took less than an hour. The only downside was the weather stripping I received was twisted and flattened in spots. I will probably replace this with a more heavy duty weather stripping, just to be on the safe side. It looks great on my 2020 Silverado, locks securely and allows the auto down tailgate to function without difficulty. The other downside was that Undercover was offering a rebate on their website, I wish it would have extended the rebate to purchases on Amazon.

Would be nice but open holes let water in
After doing lots of research I was excited to find this cover. It arrived faster than expected and was easy to install alone. However, after installing it, it appears there are pieces missing. There are 4 holes near the cab of the truck. I believe they are where the straps would attach to if you have have it folded towards the front. I’ll have to find out where to purchase these separately or find rubber plugs as lots of water does enter through them. Unfortunate as this is an otherwise great cover. The photos show the open holes I have in my cover.

I like it.
I really like this bed cover. I like that it can handle the weight if sat on by accident.

Good fit. Easy install. Water proof

The tonneau cover itself is high quality, but my box came badly damaged and one of the side rails was bent. Luckily i was able to repair myself because i work in a body shop. But never the less beware.
