are these vacuum hangers a waste?
I bought a Chinese one off eBay that a friend recommended. Within a couple weeks both sleeves had small holes in them. Maybe from weight falling, as at times it did hold.
When I pump the suction cap to my leg or hand it sticks. I think yts because it’s a flat surface. When put it over glans , it doesn’t stick . With I put the compression sleeve it has held 13 lbs. Makes me think the sleeve is holding this weight.
Has anyone gained from vacuum hanger only? How much weight? How many cm and in what time
