Product review (4 stars): Cheaper than the OEM product, and just as good, even if finicky to install
The instructions aren't clear about installing it. After many spurts of water to the face and many minutes worrying about apparent air in my water lines, I realized I needed to relax and let it work the air out. About a gallon later, I was satisfied.

The water now tastes great. I'd say it's a good value.
