I have done everything what the box has said - don’t fill past 6oz, let air out, lay flat in freezer.. and still when I thaw them out they leak everywhere! My liquid gold just got wasted from these bags! Also, I read they wrote to another customer that you need to put them on a paper towel. If that’s the case this company needs to put it on the box or make thicker bags because this is unacceptable! These bags deserve zero stars.

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 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.

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.

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.,

Maybe I didn't do enough research when pumping for my first baby, but I do not remember having bags that you could pump directly into as an option. Two words --- game changer! Having that many fewer bottles, tops, etc to wash is so helpful. I love the thickness of these bags - thick enough to feel durable but not too thick to make you feel the bulk. I received these to test as a part of the Stellar Product Testing Panel -- thanks! Highly recommend.

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.

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!

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.

Thanks to the Stellar Product Testing Panel for providing me with this breastfeeding accessories. These were the absolute best! I hate pumping because of all of the dishes that are required. This is 2 less things to wash. Additionally, I love that it saves time from pouring it from the bottle to the bag and there is no chance of spilling the liquid gold!
