I have used Lee pots for years. This last one for over a decade. A 20# pot. No drips at all. When I got this one as I got my others, I removed the spigot, put Clover on it, replaced it and turned it untill smooth and turned it every time i turned it down or off. I also always melted my raw ingot stock outside the pot.
No drips and works well.
I guess I am one of the lucky ones.
Lee for me. All the way.
