I used a breaker bar with steady pressure and it held up great. The key is drilling deep enough and tapping it in-once it bit, the bolt came out clean. No breakage, no drama.

My Allen drain plug was totally rounded. I tapped the extractor in and it locked on fast-way better grip than pliers or a regular easy-out. Removed it in minutes.

I was worried it was ‘imperial only,’ but I just used the closest metric bit I already had. Fit was fine, and it worked exactly as expected. Simple trial-and-fit.

I’m not a mechanic. Drill, tap, turn slowly-done. The markings helped me pick the right size quickly, and using a socket made it feel super solid. Worked first try.
