Review: Cuts out an extra step - I’ve been using these for months and they have been so useful! It’s cuts out the extra bottle in the pump to bottle to storage bag to bottle cycle –and that’s one less thing to wash and dry! Very easy to use, just twist it on the pump flange and clip on a bag. It works with every type of breast milk storage bag that I’ve used. And from what I’ve noticed, it does not affect suction or pull of milk at all, which is great!
Review: Helps with pumping at work - 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.

## Features

- The patented adapters (2 pc in this listing) allow you to pump directly into most popular breastmilk storage bags like Lansinoh and Nuk. Patented in both Taiwan and China, and patent pending in several countries.
- No milk loss due to transferring from collection bottles to bags; Clear in color for seeing the milk coming out during pumping.
- Fits most wide neck breastshields (Avent, Spectra S1/S2 wide mouth flanges);
- NOTE: There is stainless steel in the product. DO NOT place the product in a microwave oven or steamer bag for cleaning. Use boiling water for 2-3 min instead. DO NOT hold the clip area when you are pumping to avoid release of the bag, thus dropping the milk on the floor!
- Material: Heavy duty polypropylene(PP), BPA free. Stainless steel spring.

### ⭐⭐⭐⭐⭐ Sturdy construction
*by L***. on May 27, 2018*

I don't intend to use these until I go back to work from maternity leave, however, they're clearly a high quality product. The adaptors feel very sturdy, and the spring in the clamps is strong, yet still easy to manipulate. The packaging is meager, but more than enough to keep them safe during transit. (Thank you for not over-packing a small item!) Included was a color reference sheet with not only step-by-step instructions, but also care/cleaning information, list of compatible/incompatible bags (with pictures), and it also lists product materials and how long they're anticipated to last. As much of a chore as pumping can be, I'm looking forward to using these adaptors to make life a little simpler. Overall, I'm very impressed so far - I will be buying other replacement parts from maymom, as needed.
