REGRET: 0 WANT: 4

  • I wanted to love these. They work in a pinch but definitely reduced suction. If I had used these all the time my production would most certainly have dropped. Aug 26, 2024

    I love this brand and used a lot of their products for breast pumping. May 10, 2024

  • As an over producing, exclusive pumper, these were a game changer. I could pump with my Spectra directly into my Dr. Browns bottles! Mar 01, 2024

  • Im between love and neutral because it's a great useful product but sometimes they leak... I don't know if it's the fault of these or the valves, but milk gets stuck between the ridges. Dec 15, 2023

  • These were a game changer. I used the Spectra S1, but my sister gave me 20+ medela bottles, they never leaked and made pumping so much easier without having to buy new bottles. Oct 01, 2023

  • This helped me wash less by pumping directly into the bottle I needed it in vs having to transfer it from the pump bottle to the storage bottle. Aug 04, 2023

  • I used these to pump directly into mason jars, it was very helpful to directly pump into the glass bottles Jan 23, 2023

    Love these! I have both Medela and Spectra pumps and for whatever reason never have the right bottles. With these it doesn't matter what bottles I can find! Nov 30, 2022

  • I use these to pump from my spectra into the Medela storage bottles. Fit is perfect, although they do loosen up and need to be tightened occasionally. Oct 07, 2022

  • love being able to use these to pump from my spectra into my medela bottles for storage. Jul 11, 2022

  • Able to use it with my spectra pumping parts to fit with Dr.Brown bottles so eliminate the need to pour from spectra bottle into Dr.Brown bottles Jun 30, 2022

  • LOVED THESE to allow me to use Medela bottles on my spectra pump! I loved my pump but didn’t love the bottles that came with it. These adapters made life so much easier! May 23, 2022

  • I use the Spectra pump with the Medela bottles and these work perfect. Easy to clean and attach. Jun 12, 2021

    • Laura W.

    • Sacramento, California

    I loved these. My son was in the NICU so I was able to pump into Medela bottles they provided. Great quality and easy to use. May 30, 2021

  • These works great and saved me from having to buy all new bottles when I switched pumping machines. May 16, 2021

  • Works perfect with my spectra pump and Marella bottles. Easy to use. Mar 18, 2021

    • Heidi C.

    • west st paul, Minnesota

    I like these for being able to use the Medela bottles that are more easily bought in stores. Jan 30, 2021

  • I did have a little leaking with the adapters. Jan 25, 2021

  • Loved these, they allowed me to use my Dr Brown's bottles with my Spectra S2 breast pump. The pump originally only came with 2 bottles so before I got these I had to wash those and transfer every time Sep 12, 2020

  • I had so many Medela bottles from my 1st baby, I hated that when I switched to the Spectra to go buy all new bottles that would attach. This was the perfect option and they do fit. Apr 02, 2020

  • These are essential when you have differing bottle neck sizes and use a Spectra pump. They fit seamlessly. Jan 21, 2020

  • Skeptical because never heard of brand but works for my dr brown bottles with my spectra S1 pump It’s pretty straightforward Nov 18, 2019

  • These have been a lifesaver for this overproducer mom. I pump into the tall doc browns and it works SO nice. Just make sure they are tight when you begin pumping or you could spill. Nov 03, 2019

  • Easy to use, easy to clean, and lets me use the Medela or Dr Brown's bottles, which is great because Spectra bottles are awful. Jul 07, 2019

    • Megan B.

    • Saint Louis , Missouri

    These are great for converting spectra flanges to other bottles. That way you aren’t stuck using just one kind. Jun 04, 2019

  • My other bottles fit perfectly with no leakage May 07, 2019

    • Kat W.

    • United States of America

    These were essential to me using other brand bottles with my Spectra pump. They worked perfectly. Feb 28, 2019

  • These are great to convert Spectra flanges to fit Medela bottles! The Spectra bottles kept falling off. Feb 21, 2019

    • Pam L.

    • Hamilton, Texas

    I hate using the Spectra bottles, but love using these to adapt my Medela bottles. They are so easy to use and a breeze to clean. Feb 11, 2019

  • These adaptors are great! I can use them to pump directly from my Spectra pump flange to Dr Brown bottles. With the Tommee Tippee adaptor and this adaptor, I can pump directly into Tommee Tippee bottles too! Jan 03, 2019

    Why weeLove Milkflow Lactation Cookies:

    In case you need a valid excuse to eat cookies, here’s a really good one: boosting milk supply. Nursing moms need to fuel their bodies to keep up with the demands of milk production and new parenthood. (If you’ve been wearing the same pants for three days—we get it, girl!) While lactation teas, capsules and powders aren’t for everybody, cookies most certainly are.

    Milkflow™ from UpSpring created the first ever lactation cookies made with the dream team of ingredients: Fenugreek and Blessed Thistle. These two essentials work together to help naturally promote breast milk supply in those early days, during your baby’s growth spurts (when you’re glued to the glider for feedings!), and pumping sessions.

    Available in Oatmeal Raisin and Double Chocolate Chip, cookies are non-GMO and made in the USA with all natural ingredients. These tasty treats come in packs of two—perfect for tossing in your diaper bag for a healthy snack on the go. Each box comes with 10 packs (20 cookies total), so you’ll be able to keep your milk production going strong while keeping “Hangry Mom Running Errands” at bay. It’s a win-win.

  • Easy to use and allows you to use with the Madela bottles which I liked better. May 11, 2020

  • Allow me to use bottles from my old pump (of which I have many) with my new Spectra. Having to buy all new bottles was not some I wanted to do so I was happy to find these. Saved me lots of money! Dec 22, 2019
