Product review (3 stars): Examine the O-rings prior to installation!
Bought this  less expensive filter, its just a water filter, and installed it.  The next morning I noticed water on the shelf below the filter and drops coming from the filter cover.  I uninstalled and reinstalled the filter and it still dripped.  I took the filter out, examined the end and found one of the O-rings extremely loose around the end, the larger of the two.  I went to my local hardware store and bought an O-ring and put it on and no other problems.  Examine the O-rings prior to installation.  Other than the bad O-ring, its appears to work fine.
