Product review (4 stars): Great product and 1/4 of the price.
The filter works great with our refrigerator and the price is great. When I price checked at our local big box store this filter was $40. The only reason I didn't get it a 5 was because when we installed it and ran water through the first time a big black chunk came out and we had to run a couple of pitcher through before there was no more black. Maybe this is normal but if it is I wish they would have put that in the instructions.
