The title says it all! These milk storage bags are great! They have a double seal and I've been through 2- 100 count boxes and have had no leakage problems (though I did spill one once and YES, you CAN cry over spilt milk if you spent all that time and effort to pump! All in all, great bags and would highly recommend!

At first this bags were great, I was just pouring the milk in and freezing them because I had an abundance of milk toward the beginning. Now that my freezer stash has gone dry I’m pumping much more to keep up with my baby and I decided to start pumping directly into the bag to make it easier. The second time I pumped into the bags one of the bags fell off, spilling half the milk into my carpet. I know it was on securely, I gave it several firm tugs and it didn’t budge but then it has 4oz in there and can’t support the weight anymore. After I’m done pumping I’m taking everything to the kitchen and I drop a bag, it falls two feet to the CARPET -and every single corner starts leaking. I have no wasted more milk in this one online session than ever before

These breast milk storage bags are easy to use and well made. I have used them a lot and never had one leak or break. The bag is easy to open and seal close. I do wish the bag was a bit thicker because it isn't quite sturdy enough to consistently stand on its own when I am filling it. They lay flat nicely in the freezer which makes it easy to stack several of them. Overall, I think these are quality bags and would recommend them to other moms.

I am so disappointed! I thought I would save a few dollars on these bags - instead, I've just lost over 50oz of milk. As a working mom with low supply, this is just devastating! I do not recommend these bags. The seams are so weak, that when you freeze the milk, they split open. I now have to put all breastmilk bags in a ziploc bag to thaw, totally negating any cost savings. The zip seal is so weak that any pressure causes it will burst wide open! I'm back to using Nuk bags - they are only slightly more expensive and 100 times more reliable.

After trying some other milk storage bags, I really feel like these are the best. They are easy to open and close. I've had issues completely closing other bags, then trying to lay them flat in the freezer only to end up with a leaky mess. These bags seem to be airtight. Also easy to pour from once defrosted. The only issue I have is that the measurements don't always add up. Not sure if this is because my pump bottles have inaccurate measurements, or it is the bags. But another benefit of these bags is they are easy to label. I can use various types of pens without it bleeding or rubbing off. I've laid these flat to freeze and seems to work fine. Also sit fairly well in the fridge when filled. Also the pump attachment is a neat feature to eliminate mess.

Bags were strong and easy to use. I was able to freeze them flat (such a space saver), and it was so easy to transfer the milk from the bottle into the bag. The double seal is great. It gave me such peace of mind that the milk would not spill out (which has happened with other bags). Overall, they are great!

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.

I was recently gifted Lansinoh breast milk storage bags from the Stellar Product Testing Panel in return for an honest review. I am highly impressed with this product, the durability is great. The seal on the bags are very secure and the bags freeze great. I used my manual pump and dumped it into the bags, laid them down in the freezer until frozen and than stacked them in a soda box for upright storage. I had no issues with spillage with the bags. This product is made excellent and I highly recommend it. Thanks again Stellar product testing panel.

I received the Lansinoh Breastmilk Storage Bags through the Stellar Product Testing Panel. I wish I had these with my oldest. Pumping right into the bag is so convenient. The bags are all sealed and sterile before use. The pump adaptor easily screws into the pump connector which you then slide into the top of the bag. There is a white line that marks how far you push it in. My Medela pump work with this system. The storage bags are a thin heavy duty plastic that lay flat in the fridge or freezer. They have a double zipper seal for ultimate protection. They are super easy to travel with since they do not take up a lot of space in a cooler and the milk transfers easily to a cup or bottle. There is a tab at the top you can easily write down the date and any other info. I highly recommend these.

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.
