Pros: Durable, easy to replace parts
Cons: Expensive if you buy new
Although Medela is VERY clear that this is a one person item, I bought mine at a garage sale and then bought the horns, etc. new. It works like a champ. I went back to work full time when my son was 10 months, and this pump has done its job! The parts are easy to clean and seem to be holding up pretty well.
