Every single bag that ive thawed out has leaks in it. Lost about a gallon of breast milk. Countless hours spent pumping gone to waste. Horrible. I wish i never bought them. There are few purchases that have had such a negative impact on me. This by far is the worst decision ive ever made purchase wise. Im warning everyone i know to save them the heartache. If you dont have an oversupply, this could be detrimental.

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.

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 received this breastfeeding accessory from the Stellar Product Testing Panel and they are pretty great! Breastfeeding and pumping is a huge time commitment so anything that saves in this respect is appreciated. One simple thing that I loved was that the top of the bag is tear away instead of having to be cut like other brands. These bags also come with an adaptor so that you can pump directly into the bag, saving time and dishes! The Lansinoh breastmilk storage bags also freeze much flatter than some other bags I've tried, helping to maximize freezer space. A few times I didn't have my adaptor when pumping so had to transfer milk from a bottle to the bag, this is the one area I had a problem with. The bags are so thin that the top would fold over on itself when transferring the milk, causing some to spill. However, the positives outweigh the negatives and I am officially a Lansinoh convert.

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.

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.

The title says it all! These milk storage bags are great! They have a double seal and I've been through 2- 100 count boxes and have had no leakage problems (though I did spill one once and YES, you CAN cry over spilt milk if you spent all that time and effort to pump! All in all, great bags and would highly recommend!

These bags are amazing. u can easily fit 7 ozs of breast milk with out a worry. They are think yet thin and flimsy at the same time but in very good way. They work very good and fast when thawing the milk with warm water and also when just warming the milk with warm water. The reason I gave the bags 4 stars is because of the price.

I normally use parents choice milk storage bags. I had to purchase these in a hurry and they were the only option at the time. The bags are not worth buying. The plastic is so thin that one wrong move can tear them. Some leak on their own. I just had to save a leaking bag that started leaking while it was just sitting in the fridge. God forbid you drop one. They splat as easily as water balloons. They also won’t stand up I have to lay mine on each other in a row. I will 100% recommend buying parents choice brand for cheap cost and good quality. Parents choice has thick plastic. Never had one leak and I’ve even dropped them with no problem. They stand on their own and don’t leak during the thawing process after being frozen. Parents choice is for sure a better option.

Bags are very effective for storing in fridge and/or freezer and transporting milk. I had previously read reviews where people had reported that the bags didn't seal correctly. What I have learned from experience is that you should make sure you seal correctly by sealing the bag 2 to 3 times. I've been using these bags for at least 10months and only had 2 spills because I didn't seal the bags correctly.
