I use AVENT bottles, pacifiers and sterilizers. They are good products. But this pump does not live up to the AVENT name. First, the pumping mechanism broke after 15 days. We called AVENT and they asked me to send the pump in to have it fixed. But how was I supposed to express breast milk for a week??? Also, I do not produce tons of milk, and this pump took about 25 minutes to express each breast which makes it very inconvenient with a baby. In the end, through feedback from many friends, I chose to purchase a Medela, and I just want to share that it is amazing. I am done in 15 minutes tops. Yes, it is more expensive, but very much worth the price. I wish someone had shared this information before I bought the AVENT pump.
