I never really trusted those things along with the Fumoto valve with that gasket material ring for sealing nor the brass threads into the aluminum pan. Attempted to install one once and after seeing that the valve only makes up about 3 1/2 threads before contacting the questionable gasket. I pulled it back off and used the stock plug. Its threads not only are a closer match to the tapped hole but have a deeper engagement when installed. Still have it sitting here at the house. It was for my 2012 Silverado. To each his own though. Lots of people use them. Now if someone made them out of steel with the same length threaded shank and an undercut flange to accept an "o" ring or crush seal ,I'd be all over it.
