Bags hold up pretty good if you store them properly. A few of kin ended up having holes in them when I thawed them but I think they were banged around in freeZer

I have noticed that these bags don't hold up to thawing frozen milk as well as other brands. I have had many bags leak at the seams in which I have lost milk. Bags are not overfilled and are not mishandled.

Zipper zips tight, no problem with leaks. Same price as other storage bags. Easy to store flat in freezer for space saving. Good quality. Would purchase again. Yes, would recommend!

Love these bags. They don’t leak and are double sealed. Work great for the fridge or frozen in the freezer! Wish they were meant to hold more though. They only hold 6 ounces so that can fill up pretty quickly.

These are great bags for freezer storage, I always use the label for storage purposes as I have a high production rate. I prefer to pump into a bottle then transfer it to the bag because the bag sometimes doesn’t read right.

These bags are great for pumping, milk storage, freezing and reheating the milk too. They are reasonably priced. I wish there was a reusable plastic bag to use because I hate wasting so much plastic 

These storage bugs ended up being my favorite. They did great in the freezer. Not only that but they were easy to pour from. So no crying over spilt milk.

These bags were fairly easy to open with one hand (holding a bottle of milk in the other hand so it doesn't tip over) and they fit a good amount in them! They worked perfect for me!

Tell me Lansinoh do you actually try to make the worst breast milk storage bags known to man? 50% of mine will begin to leak. The biggest regret of my breastfeeding journey has been storing my liquid gold in your product.

Awesome product that is widely available. I have been using it to store breast milk for over 4 months now and have yet to experience any leaks. It is easy to store. Love this product and will continue to purchase.
