This is the third time I have bought these mixers. I use them to empty epoxy drums on very large commercial jobs. Drums are by no means cheap. Threads are lost a bit. Maybe a drum, maybe a faucet. Haven't tried any other faucet yet, so I'm not sure. Definitely a hassle tossing 50 gallons of resin on the side and relying on threaded taps to hold on to. They empty very quickly, so that's a big plus! 4/5 overall because I'm not sure if drums or mixers are lost.
