Warning: That cheap knockoff pouring shank cost me a full shift

I grabbed a no-name pouring shank online for about $40 less than the usual brand. Figured it was just a simple piece of steel, right? The thing cracked right at the collar on our second pour of the day, dumped about 200 pounds of iron on the floor. We had to shut down, clean the spill, and wait for a replacement. Anyone else have a story about a tool that seemed like a deal but totally wasn't?
