Here is my Undercover flex.
Nice low profile.
seals well at the tailgate.
Nice fit and finnish on latch.
Built in straps to secure panels.
Prop rods for when you need full access to bed
Cover in the full up position.
Front hold downs.
one of the things that sold me on the Flex was the fact it doesn't sit against the cab like the Bakflips when full opened. plus i found the fit and finishes on the flex are a little better than the bak's. plus it's really easy to remove the whole thing when u need all the box just remove the hold downs on either side at the front and remove it. next to no leaks too gave it a real good wash the other day spraying all the seams and seals.
