These are the best thing ever! I put them on my spectra pump in the middle of the night when I cannot use my spectra bottles because I pump more than 5 ounces on each side. They work amazing. They are also super compact to travel with and the best part… spill proof!! These are by far my favorite pumping accessory I have bought yet. Thank you lactation hub for the best products, always!

I was so excited when I saw these launch on the Lactation Hub insta. Such a wonderful, sustainable solution for pumping at work and for kiddo’s snacks in the future. The first couple of uses were FANTASTIC! The silicone bottles fit like a glove into my spectra flanges and storage was so easy with them. Fast forward to three weeks of using them, and the bottles no longer fit snuggly into my flanges. I have only ever washed and cared for them exactly as directed, but have still found them not last regardless. They have popped off TWICE now resulting in a cumulative of 16oz of breast milk wasted and completely drenched work outfits. Both times I was sitting at a desk, barely moving when the bottles fell off, and I had ensured they were in correctly before starting to pump. Any breastfeeding momma can relate to how it feels to cry over spilt milk, and boy did I! I just don’t feel like I can continue to use these and risk the chance of losing more milk and ruining more clothes while at work. Such a huge disappointment. ** Hi Hayden! That loss of milk must have been devastating! The fats in our breastmilk can sometimes make the rings/seals of the bags get extra slick. Be sure to wipe down the seals and base connectors to ensure they don't get slippery. This should help! -Jessica

I absolutely love these! They fit my Spectra flanges and connector and I just saw in their IG Reels that they also fit Medela’s so I bought 4 more. I exclusively pump and am going back to work-these are far less bulky than bringing the little bottles and far less wasteful than the single use plastic bags! I pump between 2-3 oz per side and they don’t slip or budge at all. The wide mouth makes it easy to clean. I also love that once I wean I can reuse the bags for baby food or snacks

Literally just got them in the mail and already in love. Pumping session was a breeze. I have a Spectra pump and they fit like a glove. Super secure. Im crazy tho so I just ordered 8 more :D
