The opening for this thing is too narrow. I had to buy the universal silicone attachment for the base in order to use it. Doesn't hold suction well at all even with the silicone.
I can't believe I spent money and waited for like a month for this absolute dud product. This thing has virtually no suction whatsoever. I thought it stopped working because I thought I must have reached maximum the pressure possible..
So it put it up to my arm, my stomach & my face, and I barely felt anything at all. Why it has a pressure gauge is baffling to me.
This is landfill. If I could give zero stars I would. I don't believe any of these high ratings and positive reviews are even real.
Pumps from the early 90's were infinitely more effective than anything available today.
