Installation has just been completed so this is not a long term review. Make sure you buy o-ring lube as it is not included and you need it to seat properly and not leak. So I'm going to take off a star right away because o-ring lube isn't that easy to find! The instructions don't even say you need it. When I was trying to find the right lubricant, one 3M technician told me the o-ring was butyl rubber and another said it was nitrile. So use Super Lube 92003 Silicone Grease as it is compatible with both. http://www.amazon.com/gp/product/B0081JE0OO/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1
