No matter which pump I use I will always use these for milk storage. They are way cheaper than most other brands and in my opinion outshine them all. I have never had a leak issue

These bags are great. I never had any issues with them leaking and they made storing my milk very easy. I love that you can use them directly while your pumping. I would definitely recommend these bags to all pumping moms.

These are my go to breast milk storage bags. They hold up well. In 15 months of breast feeding and pumping, I never had even one bag leak. They lay flat for easy storage and ease to thaw. I love them and even bought them for baby #2.

This bags are good for storage, very practical to use. They are very easy to use and to Store in the freeze. No leaking when pouring. I recommend the product

Love these storage bags. They hold 6oz, lay flat, and freeze easily. They're super convenient to freeze and then thaw out for a quick bottle. They were the cheapest but quality milk storage bags I found.

Over all a GREAT product! Although the measurements on the bag are not the same as what i had pumped, some bags, very rarely tho would leak, but over all i liked them , used them with both my kiddos

These were great for storage. I like the opening and that they stood upright when I added the milk to them. They freeze flat and nice for storage and make it easy to grab and go for anyone needing to feed the baby.

The Lansinoh Breastmilk Storage Bags are top-notch. They are easy to use and fill, without worrying about spilling any milk. They store flat which makes a freezer stash a breeze.

Love these bags since they have changed the design since my last baby. These bags do not leak and freeze really flat making milk storage so much easier.

These are amazing! Sealed nice so they don't leak. Perfect “Before I formed you in the womb I knew[a] you,     before you were born I set you apart;     I appointed you as a prophet to the nations.” y
