I purchased this pump after reading a lot of reviews on it and other brands. I finally decided to take a jump and go for this one. I'm glad I did. It works really well, don't have to worry about cleaning the tubing, and the flanges and bottles are really easy to clean. I gave it 4 stars only because the motor on the pump is a little loud, not loud to say you wouldn't be heard if talking, but just loud enough for someone to know something was going on, if you're trying to be discreet, but oh well. For the price, its still a good buy.
