Since the Freemie cups act as both the pump and the storage, there are fewer pieces to clean compared to the conventional electric pump that has separate flanges and storage bottles.
The Freemie has 2 cups you place directly on your breasts. They pump and store your milk and don't protrude from your body as far as a regular pump set-up. It is a discrete alternative to other electric pumps where you'd have to strip your shirt off and have bottles hanging from your breasts.
The Freemie Freedom is quieter than most electric pumps. This is especially useful when pumping outside or at work since you won't draw attention to yourself. It has changed the pumping experience of many mothers, since they feel less self-conscious when using the Freemie.
The Freemie cups are made of frosted plastic that makes it difficult to see milk while pumping. It would've been more convenient if they were transparent so mothers can just look down and check their pumping progress.
The Medela manual breast pump is useful as a 'just in case' travel companion, an inexpensive alternative when there are no electrical outlets for you to plug your electric pump in. It's also efficient for short sessions because they require less setup and cleanup compared to electric pumps.
The handle swivels a full 180 degrees. Pumping with the smaller side of the handle allows you to create quicker and shallower strokes that trigger a milk letdown (when milk is stimulated from the breast and flows quickly).
The Medela Harmony has an ergonomic swivel handle. It makes it comfortable to use over long pumping sessions since you can adjust it to whatever angle your hand feels best
The Spectra S1 is more customizable than its competitors. It has separate controls for vacuum (suction strength) and cycle (suction frequency). They are easily adjustable to imitate your baby's own nursing pattern. It also remembers your settings between sessions so you won't have to toggle the controls when you start pumping.
This Spectra breast pump has back flow protectors, making it a closed system pump. This prevents your milk from coming in contact with the pump motor to maintain your milk's sterility, and prolongs your pump motor's lifespan.
The Spectra is one of the quietest electric pumps. It only emits a gentle whirring sound. And since it has a night-light and a backlit digital LCD, it is convenient to use in the dark without waking your baby or partner sleeping nearby.
Since it saves your last session's settings, it starts at the same suction level of your last pumping session. If you ended at Level 11 which is the maximum, it will start pumping at Level 11 when you next use it. That may be surprising for some moms who are expecting a soft massage mode at first.
