"[This review was collected as part of a promotion.] I'll admit it, I was very skeptical about a manual pump. I received this pump at no cost through the Stellar Product Testing Panel and had low expectations. It's quite nice! Now, is it going to give you results like a hospital grade pump (my basis for comparison) - no. But, it is also inexpensive, portable, and I still got the milk expression I was looking for. It's amazing to just toss it into any bag vs. a huge pumping specific bag and head out. I like to keep it in my bag as "back up" if I'm out longer than expected and need to pump. It is very easy to learn to use and to clean and I find myself reaching for it more than I would have expected."
