Pros: Carrying case is convenient - Battery option is really nice
Cons: Suction weakened within the first couple months
This pump got me through some road trips due to its convenient bag and battery versatility. I personally felt like the motor weakened considerably over just a short period of time. Although many of the reviewers at the time said that Medela was happy to replace the motor, it just seemed like way to much trouble - especially after paying such a high price.
