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!

I received these breastmilk storage bags as part of the Stellar Product Testing Panel in exchange for my honest review. I am currently exclusively breastfeeding my 7 week old son. In my household, this consists of nursing and receiving breastmilk in a bottle. I nurse him on demand and pump one to two times a day in order to build a freezer stash. I am a stay at home mom and too shy to nurse in public. I like to bring breastmilk with me whenever I leave the house so having a reliable breastmilk storage bag is a MUST-HAVE. Overall, I am happy with the Lansinoh brand bags. These storage bags consist of a double zipper seal, side walls, ample writing space, and the ability to pump directly into the bags using the included adapters. These adapters work with many major brand narrow neck bottle pumps. The durability of these bags have been sufficient. They are thinner than the bags I normally buy; however, they are easy to open and close, and I have not experienced any leaks so far. I have used about 45-50 bags as reference. The only con I had with these bags came when pouring the milk into a narrow neck bottle. I did spill one time while pouring because the plastic folded in on itself causing me to miss the bottle opening. As long as I supported the bag with both hands, this was not an issue. Pumping directly into the bags was extremely easy, but not ideal for my situation. I personally did not find this feature useful because I like to store and freeze a specific amount in each bag and I do not pump consistent amounts of milk with each pumping session. I would still pump into bottles, measure out the desired amount, and then pour into the storage bags. I found the measurements to be very accurate as long as you made sure the milk is completely filling out the bottom of the bag without any folds. This can be done with a gentle shake after pouring milk into the bags or pumping directly into them. The ounces on the Lansinoh storage bags matched exactly with the bottles I use to feed my son. **See photo A - 4 oz pour** I use the cookie sheet method to freeze these bags and I have to say these are the FLATTEST breast milk storage bags I have ever used. This is by far my favorite feature about this product. I will continue to purchase this brand for this feature alone. I usually freeze 4 oz in each bag but I did fill a bag completely (to the 6 oz max) and was still able to get it flat! **See photo B - 6 oz bag frozen flat** The Lansinoh storage bags are a great addition to my breastfeeding journey. Despite the bags being thinner than the bags I previously purchased, their reliability (no leaks) and ability to freeze flat are reason enough for me to continue to use. I highly recommend these breastmilk storage bags to any mom wanting to build a freezer stash.

Thanks to the Stellar Product Testing Panel I was able to try these bags and I was very happy with them. They were a good size for storing milk and the bags are very durable. Easy open and stored in the freezer very well. I was able to fill, flatten and freeze for extended storage with no problems of leakage or bags breaking/tearing. Would definitely recommend for anyone looking for storage bags.

I was able to test these milk storage bags thanks to the Stellar Product Testing Panel. The bags feel nice and thick compared to other breastmilk storage bags which to me translates to a good durable quality. I definitely liked that I was able to pump into the bags but there was a bit of a learning curve to it and I had to be very careful in the removal of the bags. I have not transferred from bags to bottles so I can't speak to that function, but going from bottles to bags is very easy. I use my bags only for storage of excess milk at the moment, and I like that the top is nice and big for writing date and volume, and the bags freeze and flat for maximum space saving in the freezer. I have not had to unfreeze any bags yet but I sure hope they don't leak for when I do eventually thaw them. Overall I very much like these storage bags for my needs.

I received this breastfeeding accessories from the Stellar Product Testing Panel, but I purchase these regularly! I have been using Lansinoh breastmilk storage bags since my son was born 3 months ago and prior to that, I used the same bags with my daughter (now 3). They're the only brand I trust to store my previous breastmilk (especially after seeing that my sister-in-law lost about 2 months worth of her stash due to a store-brand bag being faulty). These bags are incredibly durable, don't leak if they drop on the floor (closed of course) and they can stand up on their own which makes them fantastic for re-heating or filling. They are the easiest to open, lay nice and flat in the freezer and pack easily for road trips. I highly recommend these to any new mom!

My wife uses these bags and only these bags. They are extremely durable and never had an issue. They open super easy and close securely without a fight. She never pumped directly into the bags but it is extremely easy for her and me to transfer into the bag from a bottle. I was able to freeze these flat every single time without an issue and save on freezer space. Being able to write directly on the bags with information about when the milk was produced and frozen is fantastic and makes it easy to keep in date order. Thanks to Stellar Product Testing Panel for the opportunity to test these bags out.

Overall I would say these bags are good. Only problem I have had is that a few have leaked and made quite the mess in the refrigerator. I will probably get the parents choice ones again next time, they are thicker than the lansinoh bags and I had no leakage problems.,

I absolutely love these storage bags. The plastic is flexible and not super stiff. They are easy to open and close, and even to get the air out of the bag. The plastic does not stick together like other milk bags. The curved top allow the milk to easily be poured into a bottle without having to worry about spilling. The milk bags freeze flat and don't take up as much room in the freezer like other milk bags. The top of the bag is easy to write on to display the date and ounces. Thanks to the Stellar Product Testing Panel for providing me with this breastfeeding accessories.

I received this product through the Stellar Product Testing Panel in exchange for my review. I have tried multiple breastmilk storage bag brands and these are my favorite. I do not have a Lansinoh pump so I was a bit skeptical the bags would stay put when I pumped directly into them using the adapters but I was totally wrong! The bags were easy to attach, were very secure, and never spilled once - even when I was doing chores around the house while pumping with my portable pump! Using the bags instead of bottles to pump at work has cut down on the amount of bottles I have to wash at the end of the day which is a huge bonus! The bag itself is a bit flimsier than other brands so it is a little tricky at first to pour milk into the bags if you pump into a bottle. After doing it several times, it wasnt a problem though. Pouring the milk from the bag into a bottle is a breeze though. These bags freeze very well when laid flat and dont leak. I even stack mine when freezing them. Once frozen, I like to place them upright in an organization bin by date so I never lose track of what milk I have. Overall, I think these bags are excellent quality and I would definitely recommend them to other breastfeeding Moms.

I love these storage bags and always recommend them to other moms. I have been exclusively pumping for months and these storage bags have not failed me. I love that they stand up when I am pouring milk into them. They have an awesome spot for me to write the date, time and amount directly on the bags. I love that they lay flat when I need to freeze milk. This also allows me to neatly store them together in ziplock bags instead of having them thrown all over my freezer. The double zip helps prevent leaks. I havent have one of these bags leak in the fridge or freezer. I love these bags and highly recommend them.
