Ive tried many different kinds of milk storage bags, but the Lansinoh are hands down the best. I love that they are long and oversized so I dont have spillage and waste when I seal them. I did not have any issues with leakage. I personally store mine vertically in my freezer and they fit beautifully. They thaw without leaking. Ive found they to be durable and have never had an issue when transferring milk from pumpkins bottle or silicone pump to bag. I was given this breastfeeding accessories to try as part of the Stellar Product Testing Panel.

I have purchased and used probably more than 600 of these bags. I have only had maybe 4 bags leak while defrosting in a bowl of warm water (note, I often filled with 6.5 or 7 ounces even though they state to only fill up to 6 ounces and I often jammed them wherever there was space in the freezer). I have heard of a lot more "casualties" with other brands. This is also the brand they supplied me with while we were in the NICU. Best price is always at Walmart - always a couple whole dollars cheaper than elsewhere.

I absolutely love that these storage bags that connect right to my pump. It makes pumping easy and quick plus I don't have to wash those tiny pump bottles after. They also freeze flat which saves a bunch of room in the freezer. My pump is not Lansinoh, but they still fit perfectly. If I'm not freezing the milk, the bags pour easily into the bottle. These are great! I received this breastfeeding accessories from the Stellar Product Testing Panel.

Leaking bags! These bags are cheap! I’ve had a freezer stash and been using them and every last bag has leaked! I’m furious but my feelings are more hurt than anything because I’ve had issues with you milk just for half of it to leak and get wasted. I’d never buy these again and I wish I could get a refund. I know it’s not the company’s fault but they need to make better bags!

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 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.

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.

Great product! These bags are heavy duty/thick feeing. I do pump into a bottle and then dump into thr bags just so I can stop and sit ot down if needed. The bags freeze flat vert well and have had no leak issues. Highly recommend. We received this product from the Stellar Parent Panel.

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 received a box of the Lansinoh Breastmilk Storage Bags from the Stellar Parent Panel. I was very pleased with these bags- their ease of use, durability, and storage. Even just to the touch I could tell that these bags were durable and sturdy- they would not break or tear easily. The perforated portion at the top came off easily when I was ready to use them but I loved that it was there to prevent any opening that may invoke contamination before I used them. I was pleasantly surprised that they just fit onto the pump without any additional attachments. They fit snugly and easily onto the pump to collect the milk directly from the pump. The bags had ample room for information about the contents (a date, volume, name, and time) which allowed me to organize and store breast milk easily. The bags held 6 oz/ 180 mL so there is plenty of storage, but I can easily fill less than that and still have a tight seal for storage. I had no doubts that, when I laid these bags flat to freeze, that it would leak. The ziploc top sealed tightly and nothing came out when the bag was laid down. I have no complaints about these bags and I am very glad to have them to securely store my pumped milk. (As an side, I have even grabbed these bags to put a small snack in for my kids. Ha!)
