Product review (5 stars): Easy to install and mine lasts over 5 months per ...
This is the Samsung product for their 3 door/ French door refrigerator.  Easy to install and mine lasts over 5 months per canister. Amazon definitely had the best price on them.  They usually go for just under $50 from our local stores (HH Gregg, Sears) but with the 3 pack they were $25 per unit.  Definitely worth the savings since they have to be used in the fridge's that have water systems, and this one shipment will last me over a year.  I've tried other sellers, but beware, be sure to read the reviews of the sellers (not the product) and be careful about those who promise a good price, accept your payment, and then don't deliver.  They're out there.  I've tried the knock offs of this product too, but they were a chore to put in and remove and didn't last nearly as long.  I'm sticking with the brand name that I can trust, and with Amazon for purchasing (I always feel they have my back when it comes to purchases through them.)
