I am a donor and have used over 2000 bags from April to September with only 2 leaks which I thought was great. Then, the company changed the bags to a new design to be able to pump into the bag and since then I've had to check every single bag bc they will leak from both seams on the bottom along with holes on the top. It's disappointing that something used to store precious milk is so horribly made. I tried contacting customer service and they never got back to me. Ok to buy but don't trust them and check for leaks asap so you don't lose milk.

These Lansinoh Breastmilk storage bags were easy to use. They came with adaptors that attach easily to the pump allowing you to pump breastmilk directly into the bag. However, to my surprise, my pump (Lansinoh Smartpump 2.0) worked even easier! The pump fits snuggly into the bag and the adaptor is not needed. I provided a picture to show you what I mean. This was a game changer for me. It decreased my time spent pumping by taking away the extra step of pouring breastmilk into the storage bag (which leads to less spilled milk—whoohoo!), and I now don’t have to deal with cleaning the bottles that were previously used for pumping into. It’s a win, win! After pumping, I can easily slip off the bags from the pump, seal them, label them clearly in the provided spaces on the bag, and store them neatly in the freezer. They stand up easily and I prefer to place them upright for storage. Thank you Stellar Product Testing Panel for sending me these bags to test. I will be purchasing these only from now on!

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 like these storage bags but they aren’t my favorite. The material is very thin and a little flimsy. With some other bags I can have them stand on their own to pour milk in. These bags do not stand by themselves. Spilled some milk when I thought it would stand while I poured the milk in but it collapsed. However the flimsiness of the material makes them freeze very flat and they take up VERY little space, which is my favorite feature of these! I’ve also had no issues with leaking. It’s easy to pour milk from the bag to a bottle. Also easy to pump straight into the bag with the two adapters it comes with. I couldn’t find a way to pump directly into the bag itself. All in all, it’s a good, sturdy bag. Thanks to stellar product testing panel for these bags!

I started my BF journey using Lansinoh and I live how durable they are and I'm comfortable with the labeling and I can count on them sealing properly. I have a hard time with transferring the milk from the pump to the bag so I use my suction pump to transfer it to the bag and make sure I get an accurate number on ounces Make sure to fill the Bag and stand it up to get an accurate read on ounces . I received these bags to test from Stellar Product Testing Panel!

I received my bags through the Stellar Product Testing Panel. I bought these bags back when I was nursing my son as well and loved them then too! I really enjoy being about to pump straight into the bags, makes clean up a breeze! They are very durable and easy to open and close. I like being able to freeze the bags by laying them flat so I can store more in the freezer for future use!

I wanted to like these bags. Theyre easy to open, easy to pour milk into, and easy to pump into. However, several of the bags leaked while warming frozen milk in water. I was worried that maybe the bags were filled more than 6 ounces, but my mother (who cares for my baby) said it was happening with even smaller ounce bags. I do like that they can lay flat while freezing for more efficient storage, but I store the bags standing up and reading the date/volume is upside down. My favorite part of these bags is the material - its soft, so folding the top down before sealing makes it easy to get all of the air out without getting milk in the seam. Thanks to the Stellar Product Testing Panel for providing me with this breastfeeding accessory.

I'm a big fan of these storage bags. I was fortunate to try them out as a participant in the Stellar Product Testing Panel. These bags are by far superior. They are a durable thicker material than most and I have tried a few brands. They bags freeze well too - I always put on a flat surface in the freezer so the freeze flat and are easier to store! I loved the double closures too - a must have for any mom!

Im not one to write a bad or mixed review but.. A few months ago I switched milk storage bags to the lansinoh storage bags, because they were cheaper and more ounces in a bag. I have a good stock pile and wasn't sure if I would need so much, but I'm so glad I did. Every bag that I have defrosted has had holes, ripped or torn. For one bottle I have to defrost 2-3 bags just to get a full bottle. I hope that this helps someone else who is thinking about switching storage bags. I do have other items of this brand and have no complaints..

Maybe I didn't do enough research when pumping for my first baby, but I do not remember having bags that you could pump directly into as an option. Two words --- game changer! Having that many fewer bottles, tops, etc to wash is so helpful. I love the thickness of these bags - thick enough to feel durable but not too thick to make you feel the bulk. I received these to test as a part of the Stellar Product Testing Panel -- thanks! Highly recommend.
