Product review (1 stars): Product not matching description ....
I originally bought a two pack of this dame filter back in December 2016 and absolutely had no problem with my purchase. Fast forward after installing my second filter I went back to the order and got myself the four pack ... now that I installed the new order ... IT DOES NOT FIT!!! As you can see on the images the new filter (left side) has two o-ring compared to the one o-ring on my 2016 order.

Amazon should blacklist this seller. I wonder if they audit their marketplace suppliers???
