KiindeTwist Milk Storage Bag Breast Pump and Baby Bottle Direct Pump Adapters for Major Breast Pump Brands, Leak-Free, Transfer-Free Pumping Directly Into Bag (Standard Size, Set of 6)

I love these !! What a game changer. Less pump parts to clean. Easier for my husband to warm up my breastmilk for our daughter when I’m not home since I’m pumping directly into the Kiinde bags. Which are also great, no issues. Very clean, durable, no leaks. Highly recommend

Great for directly pumping in to kiinde twist bags! Love these!

I started to use these at work and when I'm on the go. I stopped using them while pumping at work as the bags are SO expensive. I use it now when I'm traveling .

Discreet packaging, 6 adapters, and very inexpensive! They fit my spectra flanges perfectly and make for a leak proof pump session! I know where I'll be ordering from IF I need more but I think between these 6 and the 2 I already had, I'm covered.

I hate washing bottles! Pumping directly into the Kiinde storage bags was ideal for me to save time and not having to constantly wash bottles. It fits perfectly. I got 6 pieces and wish i purchased these sooner.

These work great with the new Medela freestyle pump because the old style adapters that come with the medela bags do not work with the newer pump connectors but these do!

So I love that kiinde has adaptors for all bottle types, but this one is easily threaded incorrectly. A few times we’ve used these they look screwed on correctly however, when we gave it to our daughter it leaked all over her. You just have to be thorough and do a leak test!

Unscrews while pumping, leaking valuable milk.
