Well, I got a "meaningful" response, and here it is from Uro:

"Thank you for taking the time to write us with your concerns. The overall
quality of our products has significantly changed in the last couple years.
We have 4 highly skilled engineers at our headquarters in Simi Valley, CA
that are constantly testing and improving different attributes of our
products on a daily basis. This process does take time for the results to
filter down to the end user that is actually installing our products, but we
know it will not go unnoticed.

To address your specific concern with our W123 door seals, we have been
selling them for over 15 years and have sold thousands with no issues or
problems reported. Our W123 door seals are manufactured in Thailand by a
factory also producing seals for OEM's, Febi, and Meyle just to name a few.
If you are unhappy with them we will make sure you are refunded through the
distributor where you purchased them with no questions asked.

I am also a MB fanatic and can tell you that our company cares deeply about
our products meeting your expectations and strive to do just that.
