Snapped exhaust studs and other fun issues

[darrsi]

I'd buy from a reputable supplier, not a Chinese knock-off factory selling stuff on Temu...!

Each to their own, but I've been buying some fancy tools from them over the last year, some like these that I never even knew existed, and they've worked just fine, plus my tool kit has expanded in ways I never expected at all.
Unless you have a habit of stripping or removing engine studs, how often are you gonna use these tools? My guess is they are a simple design yet very effective when put to the test.
