They store just fine. When I thaw the milk, I notice a little leaking, and it is so difficult to get the milk into the bottle from the bag without spilling the liquid gold!

I used these bags for both babies. They hold up very well. I freeze them flat for better storage. I have never experienced leaks with these bags. I highly recommend!

The bags are nice and hold a lot of milk but they don’t stand up great. Also when trying to pour out the milk it’s difficult for it to not go everywhere. The measurement on the bag also isn’t accurate with my pup bottles.

Love these bags. I use them for not only just breastmilk storage, but for homemade baby food storage too. They freeze well and are easy to store. Definitely my favorite breastmilk storage bags!

These are just ok. I received these as a gift and I used them they worked fine but didn’t feel sturdy and could easily spill and have accidents with these. They are not exactly cheap but they are reasonable .

Love the lansinoh breast milk storage bags! It keeps my breast milk secured and frozen! It has never leaked or ripped. Once you need to use it just put the bag in hot water and it ready in less then 4 min! 

They are effective and I haven't had any issues with leaks. They are reasonably priced, and you can pretty much find them anywhere. I would recommend this product.

Large volume with a double zip that doesn’t leak when going from frozen to thawed. I have found it difficult to pour from the bag and had to transfer the entire volume to another vessel instead of resealing the bag for storage.

These are my favorite bags, they store super flat when completely full which makes storage much more efficient and they thaw quickly, which is very important for us

Great product, never had an issue with milk leaking. And the milk stays fresh every time. I have no complaints about these bags they are the best I’ve tried. Exceeded my expectations!
