Maymom Conversion Kit Compatible with Medela Sonata, Freestyle Flex, Pump in Style MaxFlow Pro Pro+ Connector and Compatible with Lansinoh, MAM, Pigeon Bottles; 2pc

One of the best purchases I made. This fits my Medela Freestyle Flex and I can fit both MAM and pigeon bottles with the adapters. So much less time pumping into bags when I can pump directly into the bottles. A time life-saver for those that need to feed via bottle. Quality seems really good as well. I've been using them for over two months and they still are working great! So happy I purchased these.

I originally thought the neck was too short to fit my Pump In Style, but it turns out my husband packed the wrong ones. The adapters from this brand all look alike, so it is easy to get mixed up if you're not paying attention. But, once you have the right ones, they work great!

This works perfectly with our Medela Freestyle Flex pump! If you use Nanobebe silicon bottles, you can use these as well but you’ll need to modify them, or at least until the manufacturer makes a new “shorter” bottom section. I sanded the bottom lip down until it JUST TOUCHES the threads and now it fits perfectly! Alternatively you could double up the washer and only sand a bit, but these work sooo good now with our bottles! Just wish they made another version that fits or silicon nanobebe bottles to our Medela Freestyle Flex pump but a little elbow grease of effort and a course sander did wonders!

Fits medala pump in style and avent natural bottles. The only downfall is that it makes the bottles hit your legs when pumping because it adds so much length but it's nice to notable to wash extra bottles.

Doesn’t compromise suction and isn’t difficult to screw the parts together. Well worth it but does add an extra part to washing

Just used this for the first time and love it so far! It is so nice to be able to pump directly into my baby's bottle- a must for exclusively pumping mama's! It works with my Medela Pump in Style pump and Avent naturals bottle. I did see if the Dr browns wide neck bottles fit but they have a different thread pattern.

You need these if you are a pumping mom and using laninosh bottles but not pump. I pump once a day to give my boy a bottle and this cuts down on the medala storage bottles I was washing since we give him laninosh bottles. Works like a charm

This is amazing! I love how I can pump straight to Avent bottles from my Medela in Style pump! It fits perfect, doesnt leak. I dont even use the rubber bands that come with it. I bought a set of 2 and Im really happy with my purchase, it made my life easier😊
