Product review (5 stars): Amazon is the place to buy!
This review is more for Amazon than the filter itself.  The filters fit my Frigidaire refrigerator perfectly, as they should since they're made by and come from Frigidaire.  I got 2 of these from Amazon for the price of 1 from Frigidaire or the big box stores, and they were at my door the next day!  Amazing price and delivery time!
