Product review (5 stars): STOP paying excessive costs for refrigerator water filter
Like many others when the price of my refrigerator manufacturer's recommended water filter got to $50 for one, I thought a bit over the top.  I ordered Waterdrop using Amazon and had the "two" for half the price of one at Lowes - and it was delivered to our home in two days.  My husband installed without any issues and we are very pleased with the results.  I am pretty sensitive to the taste of water, and I can say I am good to go with this filtered water using Waterdrop.  I have already told many of my friends.  Cheers!
