I only have used the electric handpump before, but I absolutely love this pump! It is such a great value. I use it 3-4 times a week once a day to store extra milk for when I go to work, and I am able to pump 4-5 ounces from each side. the suction is very strong, and the customer service is amazing! I only had one problem with it in the 2 months I have been using it. It was the little white valve on the bottom of the flange had ripped and I didn't realize it, I called customer service and was able to switch the valve with one of the extras included in the box and we are up and running again! they are also shipping me extra valves at no cost! Awesome pump, awesome value, Awesome Customer Service!! Will definitely reccomend to my friends!
