DON'T BUY. THEY LEAK AND THEY WON'T GIVE YOU A REFUND. I DON'T WANT A REPLACEMENT IF THE ITEM DOESN'T WORK. HORRIBLE CUSTOMER SERVICE.

I bought these to pump directly into from my Medela pump (using Kiinde adapter). That ended up not being worth the hassle (easier to just pump into a plastic bottle and pour from that), but I ended up really liking these as freezer bags (they stand upright really nicely in my work freezer) or just to have for emergencies (realized I forgot ALL my bottle caps once and thank god I had these in my bag!). Also super nice to pour into/from. I don’t really trust the measurements on the side, due to it being a floppy bag. And the price point is not that great for routine use at home.

While I do kind of wish that I could have purchased only the adapter that I needed, I also see that I can try these on future bottle purchases if I need. There does not seem to be an adapter for the MaM bottles, but I will be transitioning over to the complete Kiinde bottle system very soon, so it's not needed for me. The one adapter I needed was for the Ameda Mya, which is not listed, but the one labeled for use with the AVENT and Spectra fit perfectly! Very happy to have this system to use, it is definitely worth it!

I like this product because I can attach my Lansinoh pump to it, and I can pump straight into the bag.

These were great when using to pump into the bags. As many others said, I wish I could buy just the ones I need. The other issue I had was when we needed to switch nipples on feeding from the bags, these adapters had a tendency to loosen up and milk would spill. I had to just switch over to the bottles that the nipples came from.

5 stars for the product, fits well on my spectra pump. Wish you didn’t have to buy all the others. I’ll have to donate the rest.

I have been using the Kiinde system since my first baby was born and I have to say I love it. These adapters are good quality and they work great with the Medela pump which makes it convenient to pump directly into the bag. The only draw back is that the box comes with adapters for a bunch of different pumps so I could only use 2 adapters out of the entire box. This is sad because I had to end up buying 3 sets of these so now I have a bunch of adapters that are not being used (such a waste).

I am only giving this a three because I'm so disappointed that it basically accomodates every single bottle/nipple out there on the market except for Nuk. Nuk is a great brand and popular with breastfeeding Moms so I'm a little confused as to why this is the only bottle it doesn't work with. I bought the whole system with the bags, bottle and adapter kit. I had to send them all back because it was not clear that they would not work with Nuk brand. So sad because this is a great system but I don't want to change up the nipples we use.

They definitely work with my Spectra pump and my doctor browns bottle rings and nipples but the bottle rings often leak! I only purchased these as I was on vacation and needed an alternative to bringing so many bottles. They did their job except for the leaking. I wrapped a cloth around the adapter so it wouldn’t soak my baby and my hand.
