How many times has this happened to you? You're filling up the reservoir (trans, oil, etc.) and suddenly it's full but you have a half-full funnel in your hands. How do you get that back into the jug without making a mess? Yet another patented idea from PROFORM is the trick new No-Mess funnel allowing you to fill anything without worrying about overspills. The patented ball-n-hook design shuts off flow and retains the excess fluid when lifted. U.S. Patent no. 5,950,697 & 6,341,631.
