This probably one of the worst pumps on the market. I thought I would give it a try, since I have used pumps in the past, but never a vibrating pump. This piece of junk can hardly create a vacuum, and it loses suction instantly. The vibrating tongue did nothing for me, I could hardly feel it. This pump just sucks. For anyone that wants to get into pumping, I would recommend the Head Coach pump over this waste of money.
