Agreed good product but an inexperienced person with tighten until it snaps.
Like some headbolts, the torque is different for oiled threads and dry threads.
I have a friend at a shop that was working on an explorer that broke a manifold stud off, at the end of the day it was cheaper and easier to swap engines, and it is an exhaust shop in business for many years. The customer did not want them to fix the stud so they took it to another shop that messed it up and drilled the head off center then it came back, at that point they could not fix it and out came the engine.
If you get into trouble ask for help before you make it worse not after lol
