Pros: Cheap, stimulates good let-down, easy to clean
Cons: Hand gets tired
I'm SAHM so I didn't need a really great / electric pump, just something to get a few ounces now and then for if my husband and I wanted to go out by ourselves for a few hours. I really like this pump. It was really cheap, like 20 bucks. It's easy to put together and take apart for cleaning. I haven't had any trouble with the "asterisk-shaped" flat valve. It is a manual pump so yeah, after a while your hand gets tired, but it's great for using just every once in a while. It's pretty comfortable and I get good let-down from it.
