Product review (1 stars): Contaminated, and it leaks ...
I read all the reviews and calculated I had a 50 - 50 chance of getting a good one.  Seemed like a good bet for a filter that cost half the price of competing filters.  I lost ... it leaks.

The leak was likely caused by the silicone faucet grease (which was used to coat the gasket) being contaminated with PVC shavings.  Before installing the filter, I removed the gasket, cleaned it, applied fresh grease, then installed it.  Still ... it leaks.

If the obvious contamination of a filter gasket didn't get caught by Swift Green's quality inspectors, then who knows what is going on inside the filter...  Not a good bet.
