Instruct: Classify Amazon reviews into positive or negative sentiment
Query: Now I know why it was so much cheaper

I totally agree with all the prior negative reviews. I had the same problems with unequal suction. The containers they provided to store the milk do not fit the lids properly and therefore the milk leaked. My pump quit working completely just after the 90 day warranty had past, so there went the $150 pump down the drain. The pump was so loud that I had to pump in another room with the door closed so I wouldn't wake the baby. I am very disappointed with the pump.
