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 bags are terrible. They're incredibly thin, leak when thawing, and the pour spout has a hole in it that is supposed to help with pouring, but honestly just ends up all over your counter. I've gone through at least 300 of them, and haven't had a single one do it's job.

Leaking bags! These bags are cheap! I’ve had a freezer stash and been using them and every last bag has leaked! I’m furious but my feelings are more hurt than anything because I’ve had issues with you milk just for half of it to leak and get wasted. I’d never buy these again and I wish I could get a refund. I know it’s not the company’s fault but they need to make better bags!

I really love the Lansinoh breast milk storage bags! I'm most impressed with their slim design. They freeze uniformly narrow, unlike other bags I've used, which makes it so much easier to store them in my small apartment freezer. I also like that I can pump straight into the bags even without a Lansinoh pump. I've been skeptical about this feature in the past, but the bags feel very secure on the pump adapter and I didn't worry that they would detach. Getting the bags on and off the adapters was smooth, and I like that the bags have a perforated rip-off strip at the top so I don't rip the bags while maintaining their sterilized state. Usually I don't trust the ounce gauge on the side, but the gauge was surprisingly accurate when I held up the bags. It wasn't as accurate if I set the bags on the counter. One thing I found a little awkward was the labeling area is upside down if the bags are upright - not a huge deal, but a little off-putting to the OCD part of me. Thank you to the Stellar Product Testing Panel for the opportunity to try out the Lansinoh breast milk storage bags! These opinions are my own based on my personal experience.

Horrible!!! I bought these because the price was so low .... Well you get what you pay for. I did everything exactly as recommended. Only put 5 ounces in, froze laying flat and no air. When I thawed my milk about one and every 5 bags leaked. I was so frustrated. All that hard work was waisted. Spend a little bit more money and get a different brand!

I switched to the Lansinoh brand after reading all of the great reviews. I recently started using the milk that I had frozen and these bags. Every couple of bags that I thaw out ends up leaking/having holes in it. I did not have this problem with the Parents Choice brand

THE WORST BAGS YOU CAN GET!! They leak from cheap plastic and can easily get air in them! I have used them since breast feeding and all my hard work was doe nothing!! Theae spuid bags ruined my milk supply that i built! Never again!!! DO NOT BUY THEM SAVE YOUR MONEY AND YOUR HARD WORK!!

I may have found my new favorite breastmilk bags! These bags are great. The material is nice and thick and sort of has a silky feel to it. They have a slightly larger capacity than other bags I’ve used (6 oz.) They’re easy to open and close and they have a true double zipper (see pic) so that there are no leaks. You can lay them flat for freezing and not worry about leaking before they’re frozen. This saves so much space. There are 10 bags in the pic next to an approximately 5.5 inch tall bottle (for size reference.) Unfortunately I didn’t get to try pumping directly into the bag as I don’t have a compatible pump, but I love that they include an attachment that fits most pumps out there. If I had a criticism, it would be to have a compatible attachment option for all mainstream breast pumps. I received these bags from the Stellar Product Testing Panel, but plan to buy them myself in the future! 10/10 would recommend.

The Lansinoh Breastmilk Storage Bags are made of a very durable plastic that is easy to open and close and allows me to squeeze out all the extra air for a nice seal. I like the double zipper closure which makes sure there are no leaks. I also like how I can freeze the bags flat so this saves so much room and the frozen bags are easier to stack.I love how there is a free adaptor to pump directly into the bags- so this allowed me to wash less bottles at the end of the day. I have tried out 2 other breast milk storage bags and I would have to say the Lansinoh Breastmilk Storage Bags are still my favorite. My favorite feature is the ability to freeze-flat which saves room in my freezer. Thank you to the Stellar Product Testing Panel for providing me these breastmilk storage bags to try.

I love Lansinoh storage bags! I tried a number of different bags when I was pumping for my first baby and was always disappointed with any that werent Lansinoh. These bags are a durable material, but flexible enough to be easy to pour into and pour out of again. They also ACTUALLY freeze flat- one of my pet peeves with a lot of brands is that theyre not truly flat when you freeze them. These store perfectly in the freezer. I've never had any trouble with leaking- either when filling or defrosting. I have tried pumping into the bags and it works well, but Im too nervous about accidentally tilting too far to not use a bottle instead, then pour into the bag. Im pumping again for my second now and I plan to only use these bags because they truly are that much better! Thanks to the Stellar Product testing Panel for providing me with these breastmilk bags!
