I received an email from the president of Refresh Your Water to leave a 5 star review for this filter a day after I got it and installed it.  Nice that he/she seems to be showing genuine interest in how his/her product is performing.  Honestly, I think that is a bit premature for a product that needs to see its advertised 200 gallon filtering performance before any kind of rating can be given.  Having said that, the filter feels very solid, is half the price of the OEM Kenmore filter it replaced, it fit perfectly into where the old filter came out of, the water pressure increased substantially (pretty much telling me the old filter was past its day), and after running about a gallon thru it to clear out the loose filter residue, the water is clear and tasteless just like I would expect after changing to a new filter.  For now I'll give it 4 stars.  Time will tell if it deserves a 5th.  If it doesn't make it to 200 gallons but lasts more than 100, then my take is that it is still cheaper than the Kenmore assuming its price remains constant.
