Product review (5 stars): Replacement water filters are great.
Excellent price for an expensive item.  We like to have extra filters available so they can be changed when the fridge notifies us.  We originally purchased them individually but the expense every 6 months or so was becoming too costly.  We've had excellent luck with replacement products that were not OEM and these filters are a great example of this.  They install and work perfectly.  Recommend them as a best buy.
