after 13-15 years they still perform like it was day one
i bought of pair of Active Vent retrofits -- 13-15 Years ago (!) to replace those useless turbine spinners -- i noticed brown spots on my ceiling - surprised to discover they were letting in rain and they were in good shape and spun fairly fast. i just took out the spinners - fit these retrofits in - they fit just right - fastened the standing vent pipe with some galvanized screws - easy peasy. Fast forward to 2019 - they still look great although the label has faded from being exposed to the sun - They do not let the rain in - and i live in the NYC area which saw back to back hurricanes - Irene in 2011 and the devastating Hurricane Sandy 2012. These retrofit vents will prob out last me.
