Product review (5 stars): Giving this five stars for having no trouble installing and ...
Revising my original review since I just bought the second filter at four months after the first.  The first one I purchased is still going strong!  Will have one on hand when it gives out.  Still Very Happy with this Purchase!
Giving this five stars for having no trouble installing and that my water has never come out faster.  Also five stars for the cost of this filter versus three times the cost in the big box stores, (which were not even name brand!)
Hoping this lasts the six months that it claims...but even if it only lasts four months, it is worth the price difference.
