Have had my cover for about two weeks. Looks great and was amazed at how easy it went on. Have a bed liner and was worried I would have to modify, but the cover went on perfectly. Delivery was quick and arrived in good connection.

After looking at similar products online I chose the Undercover Flex. The product is as advertised and I would recommend it. I installed it myself without any problems and it looks good on my truck. My only concern is with the front seal that is provided, in my opinion they could provide a better quality seal. The cover sits almost flush with the bed of the truck and in my opinion makes for a better look overall.

The only issue I had with installation is the need to remove the wedge shape gaskets on the rails that mounted to the trucks bed. The truck has plastic bed caps and that thickness made the opening to narrow for the cover to fit and latch properly. If not for that issue the install would have been quick. Other than that the cover works great.

This is my second Undercover Flex. I loved the one on my old truck (2016) and the new cover is even better (2020). Easy to install and high quality.

This is a very high quality product and really adds to the appearance of my 2019 F150. It was easy to install (even though) I am 73 years old. Hardest part was climbing in the back of the truck.

The cover looks great,that's why I purchased it. The fit could be better.the front and the rear of the top sticks up/isn't level. I believe it would help to have a little more adjustment in the height of the rails.where it meets the tail gate doesn't seem to be a water-tight seal.

This is a great cover. Very nice style and appearance. It installed very easy. I'm not sure it is completely rain tight but so far after a few rain storms the bed stayed pretty dry. Now I have extra lockup storage.
