Product review (5 stars): Excellent Filter - Works Fine and Doesn't Leak
This filter fit and worked great - no leaks.  While I would love to purchase more at the same time to get a better price, I don't like taking the risk of potentially getting one with a problem, and not finding that out until needing to replace 6 months or so later. So while I personally have no complaints about this particular brand and had a excellent first-time experience I potentially will continue to only purchase one at a time to be able to return within normal return period.
