Good for storage, in fridge or freezer. Able to warm milk up under running water quickly even when frozen. Never had problems with leaks. Only down side not great at self standing when pouring milked in, so always be should to hold it when pouring. Really good storage bags.

Every single bag that ive thawed out has leaks in it. Lost about a gallon of breast milk. Countless hours spent pumping gone to waste. Horrible. I wish i never bought them. There are few purchases that have had such a negative impact on me. This by far is the worst decision ive ever made purchase wise. Im warning everyone i know to save them the heartache. If you dont have an oversupply, this could be detrimental.

I recieved these bags from The Stellar Product Testing Panel, for free, in exchange for my honest review. I have used these for 2 of my 3 babies. I love that they come sealed, sterilised and ready to use. I really like the layout and space they have to write on. I also really like that they have measurements on them. I lay them flat to freeze. In all the years I've used them( going on 3 now), I've only had a few leak when thawing, but I feel it's to be expected on occasion. They came with pump attachments to pump directly into the bags, unfortunately my pump is not adaptable to use them. So I can't speak for how easy they are for that. Overall, I prefer and trust this brand.

I used these bags two and a half years ago with my first son. They worked wonderfully. I was able to date them and they were rather convenient to store and to carry. Never did i have any issues with leakages. Looking forward to use them for my daughter.

Lansinoh makes the best breastmilk storage bags out there. They are durable and easy to use. You can even pump right into the bags to avoid having to wash an extra bottle! I have tried a ton of different brands, and these definitely freeze the flattest of them all, which makes them so easy to store! I had no issues or spills transferring the milk from the bag to a bottle! They are also easy to fill because of how durable they are. The seal is strong, so I dont have to worry about leaks! Nothing is worse than losing even a drop of liquid gold! *I received these bags free for testing purposes, but all opinions are my own!

The product in general is very good. I used it with my daughter 2 years ago. This time around, I feel like the batch is not up to par. The zipper on the bag is not sticking and 3 bags so far had holes in them and started leaking as I was pouring milk into them.

Bags are very effective for storing in fridge and/or freezer and transporting milk. I had previously read reviews where people had reported that the bags didn't seal correctly. What I have learned from experience is that you should make sure you seal correctly by sealing the bag 2 to 3 times. I've been using these bags for at least 10months and only had 2 spills because I didn't seal the bags correctly.

Im so done with these bags! I worked so hard to create a freezer stash of milk for my return to work. This is the third time in the past week where Ive lost 5oz of milk due to the bag leaking when defrosting. I followed all guidelines for freezing and milk was wasted from bags containing various oz. Do not buy! What a waste! Update: I tried to post this review on their website and it did not meet their website guidelines. Trying to screen honest feedback instead of solve the problem will never buy a product from this company again after that.

Freezing the bags are easy. They freeze flat, be it on the bottom of the freezer or in the storage box thing. I have yet to defrost any so I'm not sure what will happen when I do but because of the all the neg comments on it I might have to find a way to come up with a solution in case of leaking. My least fav thing is getting the bag out of the other bag. I'd prefer them to be in a box where I can grab and pull. These have 4 bags with 25 of the freezer bags in each. The 4 bags open on the side. It's just not convenient.

I use these bags to store milked pumped while I'm at work. Strong construction prevents leaking. I love the double seal. The easy pour top make thawing and pouring milk directly into bottles so easy - I've never had any spills. For those who are new to breast milk storage, I would suggest that you store the bags flat. This will save space in your freezer and allow for quicker thawing. I would also suggest that you purchase a milk storage container to hold the frozen bags. I purchased one from a another site that allows me to use both the container and the lid.
