Product review (5 stars): but the cost is just flat out stupid..
So I've been buying the whirlpool branded one for a while, but the cost is just flat out stupid... so after reading reviews here on Amazon and elsewhere I decided to try the aftermarket alternative.  So far the water seems fine, the weight and look of the product is exactly like the Whirlpool brand.  Barring something crazy these will be my new filters and I'll keep some money in my pocket.
