No problems with leaking. I like that they hold a large amount of milk and can freeze flat. I don’t like having to transfer the milk, but they are good for my freezer stash.

I had some bags as a promo and ended up buying a whole 100 pack because of ease of use, you can write date, amount, freezes and defrosts very good. Very pleased with these bags. I have used them for over six months now

The only bags I've used and have never had any issues with leaks. I've read reviews from others that they did so maybe they received a bad batch. I've been pumping and using these bags for 9 months with no problems

I like them nothing wrong with them at all. Zip lock is great for easy access but not great for in freezing the milk as thesome milk does get wasted. But I do like this product.

I have used these breastmilk storage bags for nine months now and I wouldn't trust my "liquid gold" to any other storage bag. They are sturdy and keep my frozen milk fresh and safe. 

LANSINOH BREASTMILK STRGE BAGS 50 CT (3 pack) I love these storage bags! easy to store and super fast to thaw the milk! definitely recommend this and it’s super affordable.

Love these bags for storing pumped/expresses milk. There’s a clear place to label and they take up very little room in the freezer if you freeze with the bag laying down flat. They are durable and a great value.

These bags in particular are great for storing in the freezer. They are thick enough to not rip. I’ve tried other brands and they just fell apart, and we all know how valuable that liquid gold is!

I love these bags. They’re are very easy to fill. I have never had a spill with these. I highly recommend to lay them flat in the freezer. I would get the big pack of these. They are worth the price if you constantly store breast milk.

I wasn’t able to breastfeed a lot but the one I used worked great. I bought some for my friend and she loved them. So they must work if we both like them.
