it does work. I've used it more than once to fix gone-numb fingers (packing tape gun overuse...) and the surprise was that the needles for that win were place in my shoulder!

I've tried the dedicated woowoo-type office and the in-the-strip-mall "community access" booth-n-chairs chains (turned out to be a stealth Pfizer outfit!). I get good results in both settings.

Chris Kresser says that the term "meridian" was mistranslated. I don't even have a good guess about what's really going on with the needles and the energy. but I don't need to. for me, it works.
