Product review (5 stars): A real Money Saver
Purchased this for our Kenmore Elite french door refrigerator.  They recommend changing the filter 2x per year, at $60 per filter. We had our last fridge for 20 years - if this one lasted that long we'd spend $2400 in filters alone - which is more than we paid for the fridge itself!!  We have good well water, so the filter isn't necessary.  If you just plan on keeping the filter in your fridge for an extended time to save money, you should realize that as it becomes dirtier and dirtier, this is still what your water is running through to get to the dispenser. Yuck!  This little gadget is so-oo worth the money.
