These bags are very nice and sturdy, I've never had them break on me and I've heard from other moms that many other brands have broken on them when trying to heat up frozen milk. I can usually have them freeze very flat so they are easy to store as well. I go through very many of these so they are convenient for storing milk. The only thing I don't like about them is that they changed the shape of the bags slightly and it's harder to get an accurate measurement, so I just base my measurement off of the bottles I'm pouring from instead of the bags.

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.

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.

Thanks to the Stellar Product Testing Panel for providing me with this breastfeeding accessories. Throughout my breastfeeding and pumping journey I used the Lansinoh breastmilk storage bags. Overall, I was extremely satisfied with them. They are pretty durable. I only had one or two bags get a hole in them after they were frozen

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 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.

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.

I was lucky to receive these bags from the Stellar Product Testing Panel. I initially liked the idea of having bags that could be adapted to use with a pump, without having holes in them like some other bags, which makes it a lot easier for pouring. In the end though, it came down to feeling like more of an inconvenience and just didn't live up to using bottles. While using as just a plain old regular breast milk storage bag, there is little to complain about. I used to receive donor milk with my first child, and I recall that the Lansinoh bags leaked quite often. These ones though seem like a great improvement in durability, and I have yet to experience (and don't anticipate to) any leaking. They however do not freeze as nice and flatly as other brands I have used, though this is not a big deal at all. Speaking specifically to the pumping feature: This feature fell flat for me in several areas. I did not like being unable to set the bags down after pumping, with the pump parts still attached. That was a large inconvenience for me, however they do stand well on their own without the parts attached. While the bags were easy to attach and did fit snugly on my pump there was still some milk that worked its way up the sides between the pump and the bag (see photos), which was a little bit messy. The "grip" on these are really strong and I didn't feel worried at all that the bag would fall off. One thing I also tested was the accuracy of the measurements. They were consistently about 1/2 and ounce off from the readings on the pump bottles. So if you're just looking for a decent and reliable bag, this one feels like as good of a choice as any. If you feel like having the option to pump directly into the bag, this probably won't be so bad if it's a method you enjoy using, all things considered. I would just recommend having a bottle nearby for checking the amount pumped, if you are concerned about the accuracy of it.

I love these storage bags! I thought I'd try a different brand because I like a little variety in my life. The first bag I used of the other brand had a hole in it. I almost cried. But Lansinoh bags have never leaked! I've even dropped them on concrete and the double zipper seal stayed closed! I would recommend these bags to everyone!

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.
