I received this Porrett panel, shipped to Panama from Swiss Tropicals in early Dec 2020.
It's still in pretty good shape these days, and still does a good job mechanically filtering my sump, as an entire mechanical wall.
I hose it down pretty heavily, but never let it dry in the sun.

Being a SCUBA diver, I was always warned that any of these Neoprene type materials should never be left under UV light.
This is it below, with a shot taken today.
I admit I have allowed plant roots to grow into it. and they occasionally need to be yanked out.
Thick Dieffenbachia roots leave holes, but the filter wall is generally still pretty solid.
