These are great! And so much fun too! The manual set she is using is what we have.
And the little tiny cups are nice to use on the face and neck.
The bigger cups for the shoulder blade hardened fibrin/fibrosis adhesions that so many have around the trigger point areas.
The ones with the bigger electrical machines were advertised in FL as a non-surgical liposuction. I think the lady there called it Vac Therapy though.
I had a free demo on that machine once and it felt so good afterwards in the lower back area.
I had the hot cupping done, where they use fire, with an acupuncturist once. It, too, felt wonderful.
