Query: I love this pump...

This pump has work great for me. I don't have any sore breasts and pump plenty of milk. The only thing I don't like is the attachment for the storage cups. The cups don't screw tight and one time while at work the cup came loose and all the milk fell on me...not a good thing...I got a avent bottle and use with the pump now, better...
