Review on Maximize Efficiency and Safety with Groz 44386 Drum Bung Converter by Andrew Dickens

I needed 1 for the project I bought 3 because I'd rather have a spare on hand than wait for delivery. No work. I won't even try to crash into my trunk. Tried on 2 different barrels, still not working. Not sure if they can be returned now that they were open or not but don't waste your time/money they won't work.
