Product review (5 stars): Works perfectly!
Any time there is a drastic price difference between the "brand" and the "other" product, it makes me nervous. Based on other reviews, I decided to give the Water Sentinel filter a chance. Other reviewers had mentioned leakage on installation, and an included gasket that fixed the issue - mine had the gasket already on the filter. All I had to do was screw it into the slot, run a few gallons of water through it, and it is perfect. An excellent deal!
