What is Reddit's opinion of IRWIN Screw Extractor, Straight Flute, 6 Piece Set (53645)?

From 3.5 billion Reddit comments

I had a similar issue with my crank, I used a "straight flute" drill bit and was able to remove it. Obviously I had to get a new crank. The bike shop put it on with red Loctite.

so you can get a socket on it way down the spark plug hole..

chances are somebody cross threaded the spark plug and just cranked it in till it almost broke.. or you exerted enough force when it seized taking it out.. that you snapped the spark plug in half.

It's one of these
