Review on 🍼 Enhance and Pamper: Kangzhu 2-Cup Breast Enlargement and Massage Cupping Set, Large by Lauren Miller

I wasn't sure what to expect as I couldn't find a detailed description of these mugs but I was pleasantly surprised. The big question I had was if they have an airlock - and they do. So you can pump, unplug and they keep sucking. When I first tried mine I couldn't get either of them to suck on the pump and then accidentally discovered that the airlock valve was very firmly in the "closed" position. Using my fingers from the inside of the cup, I pressed the bottom of the valve to move it and it has worked fine ever since. The silicone rings still work very well at sealing the skin and as others have pointed out they crack and curl under higher vacuum (my pump has a pressure gauge and I usually use a 5 inHg vacuum but when I tried it down to 10 inches of mercury to go, the rings started to unroll) - but that's not a problem for me as they seem to be designed to be removed for cleaning and easy to put back on. Overall I like them and regardless of whether they have a long lasting effect or not, I don't like the feeling of using them.
