Excellent product
Ordered my Armor Flex for my 2017 F250 Super Duty and the entire process was seamless and the customer service was 5 star. Easy to install, did it myself in less than 45 minutes. I would highly recommend this product and ordering from undercoverinfo.com. Other products do not compare!

Undercover just keeps getting better
Had the "button" portion of one of the tie down straps broken on arrival. Do not think this is intrical part of the mechanism, but possibly a different packing method needed. Wouldn't have noticed but other strap has the button still attached.

Foam could be a little better in packaging, was crushed when received, also one of the brackets that holds the rod when closed was broke. Called customer service and they are sending out two new ones. Other than that Great Tonneau Cover!

Had a similar cover on a 2010 F150. Looking forward to your cover and carrying items in a safe and dry manner.

This is the 4th undercover tonneau cover I have purchased between my trucks and my sons. We come back because we like the product and it holds up well.

The undercover looks great on my 2017 Tacoma. I have researched covers for awhile and felt that this type and brand would be the best for me.
