I can't see them making much money on this niche tool, though if the page was AI generated just a few sales will be worth it.

The male model EE, who talks to himself in the comments, thinks its great:

The price is surprisingly low. This magical method for detecting faulty inductors should be expanded to other small components in smartphones and motherboards. I'd like to see a comparison with some LCR tweezers to see if this indicator is practical.
And to see if this testing method has any advantages or disadvantages compared to existing LCR tweezers.

Well... it's just a simple EM probe that you can use to tell if an inductor is being pulsed, so it's a test of the inductor and whatever is driving it.

so it's not a capacitance tester, only inductor !

That is,it can detect the following inductor faults:
1.Breakage of internal windings
2.Internal short circuit
3.Change in inductance

I think I'll have to buy one and try how it works. Maybe it's really good.
