I purchased my pump second hand from a friend as I seen the price and didn't want to pay full price for something that I might not like or that might not work for me. I've been using it since about 34 weeks and find it works perfect for me. The suction is not painful like most electric pumps. It works so well that I was able to pump 20 ounces of breast milk so far and I haven't even delivered my baby yet. It comes with storage bags so I'm able to store in the freezer Intel my baby is here and prepare for her arrival to the best possible. It's also not huge and I'm able to store it in my sitting room in its box when it's not in use on my lamp stand so I can use it anytime I have free time or my children are sleeping. Very convent for a busy mommy.
