Probably the best pump I've ever owned. The ine thing i dislike about these pumps is that sometimes the suction can pull a nut inside which can be a sudden painful experience, even more so to remove it. Yikes
Wish there can be an engineering improvement to prevent that. I do however like the another rubber pussy fittings.it is so soft and flexible.
I love the big screen and easy selector buttons and the auto on off to maintain a consistent pressure.
