I have used this brand of storage bags for almost 1 year and am very contented with it. The first time I used this double zippers, I did not squeeze out all the air before zipping it. It turned out with leaking at the bottom corner after thawing. I complained to Lansinoh and received very good customer services. My friend who used this one and gave it 5 stars, taught me how to use it. Now, I don't have the problem of leaking. And, the best thing is that I can use regular ballpen to write on the bag. For the other brands, you need a marker which stains in smell or even need a label. More important, it's BPA-free and I don't have to worry about warming up it in a glass of hot water. Now, I exclusively use Lansinoh storage bags for storing milk.

I've been back to work about 3 wks now and started using these bags right beforehand. I just finished a 50 count box. I've lost 3 bags of milk due to severe leaking when thawing, so I'm a bit irritated as I do view my milk as liquid gold since it takes a lot of pumping to get what I need. I only store 4 oz at a time, so I know overfilling is not the problem. I am researching other brands but may still give this one another try as I really like everything else about them.

At first I stored about 10 bags (frozen flat) in a plastic container in the freezer, and now I store them per 20 or so in a freezer Ziplock bag. That way I never had any leaks during defrosting. I think you can get leaks by small punctures into the bags from other items in the freezer. The double-bagging also preserves more of the good taste.

The sides of the bags are not able to withstand the freezing and thawing process. The milk leaks out of the sides when thawing out milk, and if you thaw the milk in water to expidite the process the water then contaminates the milk. I have had to switch storage systems since I work and store the milk for later use.

I tried several bags before giving up and using a different brand. VERY frustrating to watch your hard pumped milk going down the drain...

I love these pre-sterilized bags. They are so convenient and you can store a generous amount of milk in each bag (I can never completely fill one when I pump). I recommend these to any working mom!

These are great, easy to fill, freez flat, and they they don't take up much room in the freezer, and I haven't had any leak. as a mom who is going back to work, I feel so much better knowing that my baby is still going to get getting my milk when I am not there.

My daughter is only seven weeks old and I've not given her bottles yet, but as far as the ease of use, these bags are fantastic. I've also tried Medela bags and I prefer the Lansinoh.

With my first son I breastfeed and pumped for 13 months. This was the only brand that I would use that was not crap. I used 4 other brands and didn't like them, but this one I LOVE!!! You can zip the top shut like a zip lock bag. Excellent way to store breast milk.

The Lansinoh storage bags are by far the best! I have used Avent storage cups and Medela bags and find Lansinoh to be the best! I used them for 9+ months to store milk for my first daughter. I can't count how many boxes of bags we went through and never had a leak or hole! I am now using them to store milk for my second daughter (7 weeks old) and have already used one box without any holes or leaks. I have been freezing milk for the last 6 weeks to prepare for my return to work and have yet to have issues with freezer burn. I love that they can be clearly marked with the date and amount of milk. I also love how easy it is to transfer the milk to a bottle. Not only are they cheaper than other brands, but they are simply the best product for storing milk.
