1.9 stars. Typical 1-star review excerpt: “I’d like to discuss this matter with the numb-skull who though that it would be more friendly to the polar bears to pour gas all over oneself rather than venting the can as it has been done for years…through a vent hole.” LINK
So stick with the vent hole method if possible! 1 spill is worth 1000 ventings. Go with the ventings.
