The silicone collection cups are by far my favorite pump to use. I highly recommend getting extras to allow for more grace period between uses, if two are dirty you can still pump using the spares.

Had to have an extra set so cleaning wasn't so stressful!

Having multiple sets is so helpful with pumping during the workweek!!

If you have and use the silicone collection cups, definitely invest in the spare parts! It's extremely helpful to have another set ready especially when on the go.

Love having the spare parts to cut down on washing.
