Product review (2 stars): If you have well water, skip this filter
I decided to try this filter after the authentic Samsung DA29-00003G filters stopped fitting in my fridge for some reason (a problem many others started having as noted in the reviews), I received it and installed it in the fridge and it actually fit! +1 for the Waterfall. But then I ran a bunch of water through the filter as the instructions said and drank some. It had a HORRIBLE sulfur smell/taste. Ran more water through and still no good.

This filter actually made my water taste WORSE than if I just drink it straight from the faucet. I emailed the company and they were kind enough to offer a replacement but it had the same problem. They issued me a refund, which I'm happy with, and their great customer support kept me from giving this a 1-star review. But if you have well water, I'd pass on this one. The search continues...
