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 have had the same issues with bags leaking when thawing. I pumped for seven months and as we are thawing bags most are leaking. I would not use these again for this reason. They do not hold up when freezing. I ran water in to see why they were leaking and could see water shooting out from two or more holes.

After trying some other milk storage bags, I really feel like these are the best. They are easy to open and close. I've had issues completely closing other bags, then trying to lay them flat in the freezer only to end up with a leaky mess. These bags seem to be airtight. Also easy to pour from once defrosted. The only issue I have is that the measurements don't always add up. Not sure if this is because my pump bottles have inaccurate measurements, or it is the bags. But another benefit of these bags is they are easy to label. I can use various types of pens without it bleeding or rubbing off. I've laid these flat to freeze and seems to work fine. Also sit fairly well in the fridge when filled. Also the pump attachment is a neat feature to eliminate mess. Thanks to the Stellar Product Testing Panel for providing me with this breastfeeding accessories.

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!!

Since I produce low milk supply, I thought that I wasn't going to use this storage bag for my breastmilk. Once my milk supply increases, this bag is so useful! I used the sampler & liked the product! The opening (once unzip) is a good size since my bottle has a wide circumference. I just have to be careful when pouring it out into a bottle for when the baby need to drink it. I'm also glad that there's an area where I can put the name, date, time, & volume on it.

I usually don’t even leave reviews but I wanted to warn other moms to that I definitely wouldn’t purchase this brand ever again %26 I would advise anyone not to purchase either, They were fine to store my breast milk in but when I went to defrost them they had a hole in the side/seams and my milk leaks out. Also not my first breastfed child so I know I didn’t over fill the bag or do anything else wrong. I was so upset as you know it takes so much time and effort to pump %26 soon as I go to feed my baby BOOM no milk in the bag left. Ugh I have used the entire pack, now I have to figure out how to safely defrost all this milk I have. Not worth it! Spend a few extra bucks for the medela brand

Thanks to the Stellar Product Panel for providing me these breastmilk storage bags. I love love love that you can pump directly into these bags with the included adapter with almost any pump--I have struggled to build any kind of stash of breastmilk because an ounce or two of milk is hard to justify washing bottles and transferring to storage bags, but this eliminates milk lost in that process and makes clean up so much easier which is always a huge win in my book. As long as you have room for one bag in your freezer, these are easy to freeze flat and stack anywhere in the freezer after the initial freeze. The bags are good quality and I've had no leaks or anything to report. Great quality and easy to use!

I love the convenience of pumping right into the bag. I am thankful for Stellar Product Testing Panel for the Lansinoh bags and adapter. I greatly appreciated not having to wash any pumping bottles. I am still trying to learn what the best way to switch if I pumped more than 6 ounces on a side. I made a few messes trying to just swap the full bag with an empty one, mid-pump. The bags easily poured into the babies bottle and I was able to freeze any extra milk. The bags easily froze flat minimizing the room needed in the freezer.

These bags are okay. I’ve had quite a few leak while thawing milk. I prefer my Medela bags because they are thicker but these are a little cheaper which is nice.

The plastic is thick and durable. The double ziplock also prevents leaks I really like them. Been using them with all 3 of my kids and they work best compared to others
