Wait, I think there's something off here. A click type wrench clicking early at 4 Nm under is a big deal, but that sounds more like the tool was dropped or abused, not just age. I've had a cheap one for years and checked it against a beam style every few months, and it stayed within a Nm until I accidentally knocked it off the bench. Then it was way off, like yours. So the real issue might be that you need to store them in a case and never let them bang around, plus get in the habit of testing them before big jobs, not just trusting the click.

That AI logo thing got me too. Dropped $120 on one that promised "pro level branding" and got like 18 versions of the same weird triangle blob. My neighbor who does graphic design on the side laughed when I showed her and fixed it over coffee for $40 plus a pack of good donuts. The text was always either missing letters or just straight up nonsense, no matter what I typed in the prompt. Honestly the only thing those tools are good for is making me appreciate real designers way more.
