Having worked in aerospace and managed groups with many inventors, they get carried away with their expectations for their invention, and are paranoid that anyonne who criticises it just doesen't understand. They often conduct misleading tests that prove mothing.
A product needs to have some independent testing and evaluation for not only functionality, but maintainability and producability. I'd be very concerned about puttinng that thing on my lens and having the plastic turn to goo in hot and humid weather, just because the inventor got sold on a plastic to use by a salesman from a big company. We got caught once with a new engineering thermoplastic from a major company that was supposed to replace expensive thermoset plastics. We ran standard tests on it, but when it came time to assemble the parts made from it, they would not fit. The cleaning fluids used in our manufacturing process caused the material to stress relieve , which means warp and change shape and size. It was a expensive mess, just because we did not know they used that particular chemical in their cleaning process.
The material was guaranteed to last 50 years, so I ran some pieces thru my dishwasher at home, and after a dozen times they cracked. Even experienced and careful people get fooled, a small time inventor has even less of a chance.
