No one's asking for glowing feedback. The history behind their design thusfar has been made clear. Knowing or even making a statement as to it's longevity cannot be knowingly made because it's an unknown variable. I have no complaints with the plastic lense on my 9 year old Audi. How many here have a second car that's less than 5 years old and has yellowing issues? Of course there's going to be unknown variables here because there hasn't been a long term test process involved. It doesn't mean it won't work not does it mean it will. What is known is results achieved from Andy's prototypes. The manufacturer's process will also be much more refined than Andy's garage made prototypes. How many times is it necessary to say that the intent of this thread was to see what level of interest there is in this new product. Those that are not interested can say so. Those that have specific questions can ask them directly and respectfully. Those that aren't impressed with them can say that too - respectfully. As adults we should be able to get our point across quite easily without having to resort to insults. Constructive criticism is always welcomed although the delivery of such by some could use a little work.
