Product review (4 stars): Very reliable and functional water filter.
We're on our 4th filter since we've owned the fridge and I'm very happy with the results. I change them out every six months as recommended, regardless of flow or taste. We have had no issues with the four we've used and while we do tend to have pretty good water quality (I live in Oregon), there is still a distinct chlorine taste from the tap that isn't present in the filtered water.

The only drawback I've seen is pretty minor but I'll mention it anyway; the pressure/flow varies from filter to filter. From the same pack of 3, I had one that flowed somewhat slowly and borderline weak and the next one had pressure so hard it would splash out of small cups. To me that indicates a fair amount of variation in manufacturing which isn't good, but all in all, I'm happy with the product.
