Product review (5 stars): We're not dead yet
We're drinking water filtered through this thing and we're not dead yet.  'Nuff said?  Seriously, I'm not sure what else to say about it.  I am using it on a Samsung french door-style refrigerator where the filter is easy access in the front (an improvement on my previous fridge where the filter was located in back).  It is not as easy to turn and remove as I would like but not terribly arduous either, and the tight click into place at least assures that I know when it is where it should be.  The filter claims to work for 300 gallons but offers the disclaimer that this number may be smaller in areas with water that has a higher need for filtration.  In any case, when obtaining a little drinking water from the fridge here and there, it is impossible to keep track and know if we got 200, 250, 300 or even 350 gallons so I will just have to trust that it works for "around 300 gallons".  The water it filters appears to the naked eye to be clear and tastes great and I can tell a difference in taste from tap water, which assures me that it is working as I would hope a water filter would work.
