These are easy to use and we haven't had any issues with leaking. I would recommend measuring with a bottle rather than the bag, because they are quite different.

I have started using my frozen milk and at least half of my bags have holes or are leaking. I would not recommend these bags at all. I am so disappointed that I am losing my hard earned milk down the drain.

Another great product by Lansinoh. They are comparable to other bags and I have never had any issues. I switch to different bags often and I have never had leaking issues with this product. The price is comparable to other bags.

Lots of baggies for the price, great value! Also I haven't had any issues with leaking or bags breaking. Plenty of room to write date I also sharpie in how many ounces since I lay the bags flat in the freezer. I would definitely recommend to anyone!

Thick plastic with a great seal, the bags are sturdy and I’ve never had a spill! Easy to use and label, and shove in my bag on the way to work. This is a brand that I have grown to trust and would recommend.

These are by far my favorite Lansinoh product. They are perfect for freezing my breast milk for my little one. I use them all the time when I pump at work. I have the lansinoh breast pump so I can just pump straight into the bag, so convenient.

I love these for storing breast milk, they freeze flat for easy storage and leave room for a stockpile, bursing moms know what i mean there! Just be careful not to over fill because they tend to split at the seams if you over fill them.

These worked well to store my milk in the freezer for daycare. I didn’t pump directly into the bag but poured into them. I had no issues with anything leaking. I liked that they had a spot to label them.

I used this brand of milk storage bags primarily when I was pumping and storing excess breast milk. I did not run into any leaking. I highly recommend this brand to any mom.

Great for storing breastmilk, especially if stored horizontally. The milk freezes in a thinner, flatter shape and makes it easier to stack together and also thaw later.
