Didn't fit my screwup
It was too big. All my googling said this was the size I needed and it wasn't. Extra tool I guess

What a joke and disappointment
First time use, 1 hole to clean the threads. Broke in half into the hole. Cannot be drilled out, lucky for me I kept a very old pointy plier, so I could fiddle it out, otherwise I would have ended up with a $1000 service bill or more. I cannot believe that even big brands cannot be trusted anymore.

Snapped inside threads
Snapped inside threads. Impossible to remove. Absolute junk. 1 star is too high.
