Terrible / non existent service. We purchased these screens in Puerto Vallarta Mexico from their representative here - Elmer Lugano. Now, one of the retraction springs has broken. We've been waiting 2 weeks for a repair - at this point he won't even answer our calls. Keeps promising repair every day, but never comes. I have recommended these screens to dozens of people over the years, but without any kind of adequate service when they have a problem, I will never recommend them again.
