Overall I liked this breast pump for a non electric one. I was skeptical at first but it was actually pretty easy to use- you just have to get in the pumping rhythm. I think this pump is best for seasoned breast pumpers who know what they are doing and where milk comes semi easy to them. If you clog easily or it is hard to get an electric one to work with you this may be more difficult and uncomfortable then it needs to be. But, if milk flows easily this is a great way to do it on the go and with minimal supplies. It suctions well to the breast when attached properly and it is easy to get the milk to start pumping out if you have a good flow. I didn’t realize how easy a manual one would be but this is great and highly suggested. It also fits most standard milk bags so even though it comes with 2 you can use whatever ones you have around the house or get at the store. I reviewed this item at a discount in exchange for an honest review.
