This is a great pump because it is easy to operate manually and has minimal parts for cleaning. I owned several pumps before this one and found all the pieces and tubes to be so annoying to clean. The Avent manual pump is compact and easy to slip in your purse or diaper bag. I traveled with this to hawaii (with my husband and bro-inlaws) and carried it with me on excursions of all sorts and no-one even knew I had it or was pumping through out the trip. It was great and I recommend it to all new or experienced moms!
