## Questions & Answers

**Q: Does this work with spectra S2 plus pump**
A: They surely do.

**Q: Do these work with Madela bags?**
A: HI, As is, the device will not work with Medela bags because the top rim of the bag is farther than 2 cm from the zipper line.

If you really want to use Medela bags with this adapter, you might tear apart the side rims of the top part of the bag. The top part means the area above the zipper line. Fold the top part outwards so the bag can be clamped by the adapter below the zipper line. After the side rims are torn apart, the Medela bag will be similar to a "Lansinoh" bag. See photos of the listing for instructions on installing 'Lansinoh" type of bags.

**Q: Clhas anyone used these with rhe spectra pump?**
A: Yes and it fits well.  Just make sure to clip below the seal.

**Q: Does this work with the NUK storage bags?**
A: Yes it does

## Customer Reviews

### ⭐⭐⭐⭐⭐ Helps with pumping at work
*by T***8 on February 21, 2025*

These have been an absolute lifesaver for me as a working mom. Pumping at work can already feel overwhelming, but this adapter has streamlined the process and made it so much more manageable. Eliminating the step of pouring from bottles into storage bags has reduced stress and the chance of spilling. When you pump at work every minute counts and these help streamline the process and cut down on my time away from my desk.These fit seamlessly with my Spectra and Baby Buddha pumps and I have had no leaking issues.

### ⭐⭐⭐⭐⭐ Great for travel
*by N***E on November 13, 2024*

I purchased these specifically for traveling. I hate having to haul around all the pump parts - they take up so much space. So instead of having to carry around storage bottles, I travel with these and milk bags and it saves significant space in my pump bag. The clips are strong so I don't ever worry about the milk bag slipping (even when it's quite full). Overall, very happy with these.

### ⭐⭐⭐⭐⭐ Saves 1 minute, which is priceless
*by M***L on September 18, 2024*

The media could not be loaded. I use these instead of the spectra s1 bottles attached to momcozy milk storage bags to save myself the hassle of transferring from bottle to bag. I am an overproducer so I don’t sweat the mls I lose out on the transfer but I know for some moms, every drop is so important. I don’t find I need the silicone rings used to help grip but I’m sure if you produce that much (more than 180 ml per breast), the rings could be useful. I just tighten as much as I can.
