Product review (2 stars): Works okay for the price
It fit fine.  First few glasses started out with black color to the water.  This pretty much dissipated with the 4th 8 oz glass, but spooked me a bit.  We don't think the water tastes as good as from the OEM filter that came with our Whirlpool fridge, but they're 1/4 to 1/3 the price.  Whirlpool is awfully proud of their filters, aren't they?  We use the filtered water from the fridge for cooking and making strong coffee and drink mostly bottled Dasani, so this is probably acceptable for the price compared to about $50 ea for the OEM.
