Sold me a filter that was already written down as defective, and returned by a previous buyer.
Sold me a filter that was already written down as defective, and returned by a previous buyer. They even wrote the dates when it was bought and returned. I tried it and the smell was horrible, like a car that was leaking gasoline and oil Who sells someone something that’s already defective.
