I recently purchased a RV water filter that did not work. I was able to flush the filter but then the water flow completely stopped.
Something was blocking the flow of water apparently within the filter. I wrote a polite short factual review giving a poor rating. My review was never published and I noticed that there are no negative reviews of any product on their web site. Over the years I've spent a fair amount of money with them.
However no more as I am done with them.
Most of the items that they sell can be purchased at Amazon and Amazon does not suppress negative reviews.
Monetary Loss: $20.
