Maymom Breastmilk Storage Bag Adapters Compatible with Spectra S1, S2 Pumps ; 2 Duckbill Valves Included; Clear BPA Free Material; Boiling Water OK; Do Not Use Microwave or Steamer Bag to Sanitize

Perfect and easy. Helps when u pump too much to fit the small bottles that comes with pumps

It’s easy to use and fits our Motif breastmilk bags wells. It doesn’t leak as long as you stay mostly upright while pumping. It’s great because you can pump directly into the bag instead of pumping into a bottle!

Works really well with up & up brand bags, perfect for travel.

Works pretty well. I just wish the space between the opening and the spring inside the clip was longer. It’s so shallow that the opening doesn’t go very far into the bag, and I’m always afraid I’ll end up spilling some milk.

Love how easy this is to use and clean! Cant live without it now!

Its works with "Maymom Pump Parts Spectra S2 Flange Valve Tube Bottle Backflow Protector." States not to use with "Medela" bags but we just cut them short and they clip on extremely well.

I love these! It makes it easy to pump and store. I seriously get tired of finding the storage bottles that came with my pump and cleaning them constantly so with these I pump right into my bags. I use the Nanobebe bags because I was gifted the bottle set, so I’m sure they work with other brands of bags. These were well worth the purchase.

These are a game changer! I use them with my spectra and they are a breeze. I pump directly into the bags which is SO much easier, faster and less stuff to wash. These are the first thing I recommend to my mom friends returning to work.
