Not good quality
This set looked promising initially. When it arrived, I hoped to use it immediately as I am experiencing swelling in my knee-  however, the tube attachment and plug that is supposed to fit into the end of it, does not fit.  Therefore the tube is useless.  I tried the cups with the pump handle only and it works while the cup is attached to the pump-  when the pump is removed the cups lose suction.  So they work with the handle attached, but will not stay on otherwise.  I returned these.  Depends on what you will use this for...  As a massage therapist, I hope to find a better quality set to use in my practice.
