Product review (5 stars): Great Filter, Great Price
Don't listen to these idiots giving bad reviews of this product, since it's obviously operator error on their part.  Installs perfectly on first try, as described in the enclosed directions.  Increased water flow was noticeable immediately, as was excellent taste and smell.  Great little filter at a great price.  Don't bother with the $50 OEM replacements, get one of these instead.
