Shepherd continous plastic hinges

[HighTechRedneck]

Does anybody here have any experience with these?  Their specs and info looks pretty good, but I wonder if they really do hold up any better than rubber hinges.  If they do, they would work very nicely on fabricating the bay doors on my RTS.  Their specifications indicate that the hinge load strength is 100# per linear inch, so no problem there.

They state:

"Shepherd Plastic Hinges are advanced one-piece, molded, plastic, pinless hinges created for silent and maintenance-free service with never a need for lubrication. They will not fatigue or deteriorate even in wet or corrosive environments. Shepherd plastic hinges are even protected against the damaging effects of sunlight with superior UV resistance."

In the PDF brochure they state:

"Flex-tested for millions of cycles, one piece Shepherd Continuous Hinges may be used in place of metal piano hinges for bind-free and pinchless operation."

High Tech,

     I considered some of these once.  My worry was that the sun may break them down after awhile and make them brittle enough to crack apart.                        Just my .02$ though.
