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.

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.

I have used many other Lansinoh products and have been very pleased with them, but NOT these! I am a strictly pumping momma and because of that, I store moat of my milk. These are not worth the money, I have frozen these bags and have gone to thaw them out for use and they have holes! I've lost quite a bit of milk because of this. My sister and sister-in-law have had the same problems with these bags. If you feel them compared to other brand bags, you can feel the difference. The lansinoh are much thinner compared to Nuk brand or Medela brand bags (others that I've used). Take my word for it, do not buy these. I recommend either the Nuk or Medela bags!

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!

I've used other milk storage bags in the past, but these Lansinoh bags have some really nice features that my previous brand did not. I love that there is a double seal - so many times I've thought I fully closed the bag, only to see some leak out, which is heartbreaking. The bags are easy to open and are a nice durable material. I use the Lansinoh manual pump, and was able to fit the pump into the bag, and directly pump into the bag with no need to use a bottle. This was great, as I did not have any additional pieces to have to wash later. It was easy to remove the pump when done with no spillage. I also use a silicone manual pump on the side I'm not pumping or feeding on, to catch anything that may come out. I was able to easily transfer the milk from there into the bags as well. You can freeze the bags flat, which saves so much space in your freezer. I will definitely continue to use these bags going forward. Thanks to the Stellar Product Testing Panel for providing me with this breastfeeding accessory.

I was sent these bags to review as part of the Stellars review panel but all opinions are my own. I like the Lansinoh Breastmilk Storage Bags better than any other bag Ive tried. I have 5 kids and Ive pumped for the last three. So Ive used ALOT of bags and filled up my freezers. Ive never had a leak or a single problem with any of the hundreds Ive used. And theres an adaptor to pump directly into the bag. Talk about a game changer!!

I received this breastfeeding accessories from the Stellar Product Testing Panel. These bags are very durable and don't tear or break open when you freeze them. The perforated top allows you to open them without scissors like some brands. Easy to pour milk in or pump right into the bag. The best part is they freeze flat making thawing go faster and storing easier.

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! Thanks to the Stellar Product Testing Panel for providing me with this breastfeeding accessories.

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.

As a third time pumping mom, I find these milk storage bags to be far superior to other brands I have tried. The pump adapters allowing me to pump directly into the bag is a huge plus! It is easy to set up, saves time from washing extra parts and anything that saves time is a huge win in my book. They freeze flat, the bags dont break or leak after thawing and pouring into bottles is spill free. Thanks to the Stellar Product Testing Panel for gifting me these milk storage bags, I have found my new go-to milk bags!
