You're just seeing these NOW?
I've had one since at least 2018 (I've broken 2-3 from accidental falls). Shango and numerous VKers have been using these for years.
They're good for working on SS gear. I use mine mostly for ESR tests, checking pF caps below what my Heathkit C3 can accurately measure, inductors, and for checking PN junction based parts with 3 terminals or less and identifying parts I don't feel like searching datasheets for.
Not sure what's sexy about a PCB with a LCD and a single button... Unless there's some hidden Easter egg to get naked ladies to dance on that LCD screen.
I know there's a calibration mode easter egg that appears if you short all 3 terminals and push the button...
