Query: Leaks

Works fine if you don't mind 5% of the water leaking out. Also no accompanying instructions and it cracks easily if you tighten hard trying to stop the leaking. Mine cracked and I had to shave and sand the clear male end to reduce the leaking. Just to clarify, it leaked before it cracked. Other than that, it filters effectively, cleans easily and probably deserves 2 1/2 stars. I would have returned it but couldn't find another similar product on the market.
