Review on Universal Gas Can Vent Caps Retrofit Kit 3-Pack, Improves Flow for Quicker Refills, Durable Stainless Steel Replacement Vent Valve with Silicone Rubber Cap for Effective Fuel Tank Enhancement by June Reeves

First, the packaging is great. It looks like a very well made product and not the usual plastic junk. I can see that the vent will actually last a very long time, but I'm not sure about the little rubber (plastic?) cover. It's not a very tight fit, so I can imagine it falling off and being lost as it stretches over time. (I see other reviewers had this issue, but not me. Not yet). One star deducted for that. Either a slightly better design or a few extra plastic spare caps would have given it five stars. The point is I like it. SO EASY to install; Just a couple of minutes. Screws for a secure hold!
