Broke at the hand pump neck. Waste of money in my opinion. I went and bought another set that was only 18 dollars. It's the ordinary one you see doctors hand around their neck. Works a lot better and is a lot more efficient than this one. The reason why I say this one is less efficient is because you have to hold the pump with one hand and that hand is tied up. I find it cumbersome because of the pump. I'm faster with the cheaper one.
