Perfect storage
These bags are perfect for storing milk to add to bottles later! The size is nice and the texture of the bags are a lot better than the ones I’ve used in the past. They’re easy to store, do not take up a lot of room and have perfect spots to write down time and date.

Easily store in the freezer, no pour spout for mil
These storage bags have worked great for my nursing journey! They can hold quite a bit of milk although I wouldn’t recommend overfilling it because it definitely expands the longer they’re stored frozen. I prefer the thinner design of these bags as opposed to thicker because I feel like they store better long term. I found it easy to get all of the air out of the bag each time and the ziplock stayed sealed. One of the negatives I have is about the measurement guide being off but honestly just about every breast milk storage bag is that way. The measurements just never line up properly with what the bottle will say after a pumping session. It is almost always off by at least 2 oz. For example: what you would be 4 oz in the bottle will measure as 6 oz or more after being poured into the bag. These are also missing any type of pouring spout to get the milk out easier after warming.

Great for milk storage, easy to defrost
I liked the flexible plastic of these bags, it makes defrosting easier. It does make pouring into the bags a bit difficult, but it froze easier too with the malleable bags. I haven't encountered any spills using these bags.

Leaky
The bags are easy to fill and seal but when thawing i had several that leaked and caused me to lose all of that milk. Had to start thawing in a huge container to make sure it didnt spill out of the leaks.

This are awful. They’re so thin and then collapse in your hand while trying to pour from the pump. I’ve lost so many ounces because of it. They also don’t sit upright because they’re so thin

Favorite
These were my favorite breast milk storage bags of all time. They were very easy to use and they froze very flat. The double seal was great and they were very affordable.

Some flaws but otherwise great product!
These are some of my favorite milk bags! They are amazing quality and hold a lot of milk. The only thing I don’t like is that sometimes it pours the milk out weird and I’ve lost milk for that reason. Other than that, they’re great!

Best Milk Bags Ever
These are my favorite bags for milk storage. They have the ability to lay flat, no issues with leakage onto other bags/the freezer. Due to them laying flat they thaw pretty quickly.

Large capacity
The bags are a good size. The plastic it's made out of in my opinion is a bit thin! I do like how they freeze flat when laid flat. They store nicely. But unfortunately because the plastic is thin I do have bags that leak when I thaw them out! They're also easy to label and hold a decent amount of milk.

Not for Me
Although these are super popular they did not work for me. These are my least favorite storage bags. They’re thin and flimsy. Very easy to spill milk out of and hard to get air bubbles out. Now they do lay flat and save room in the freezer, but I wouldn’t purchase again.

Worked great but some leaked
Very easy to use and the bags are durable but flimsy. The measurements are not accurate. They worked well though storing milk flat in the freezer. I did have only a couple that somehow had a busted seam and leaked so just be cautious but it was only maybe 1 or 2 out of the bunch. I used these until I got free bags from insurance and these actually fit better in the tray I used to hold them.

Great for storage be careful when pouring!
These bags work great for storing breastmilk! They are able to freeze flat and stack nicely. I do wish they had a separate pull tab with pour spout like other brands as I have had the bags collapse when pouring milk into a bottle resulting in spilled milk.

Leaks! Leaks! Leaks!
I've tried a few different brands of breastmilk bags now, and unfortunately these are by far the worst I have used. I actually did not realize these bags leaked so much until a few months after using them. I started thawing a few and every single one leaked!! I never overfilled the bags or anything, and I always pushed out as much air as possible before freezing. The only upside to these bags are that they freeze very flat and are easy to stack into bricks, they also have a nice clear place to label. I just wish they actually worked.

Holes in bags
I have noticed holes in the bags, after I thaw them out to feed my child. I have lost ounces of milk and its very irritating as much work I put into pumping those ounces. I have switched to Zommee and Motif brand bags, they are thicker and alot better to store breastmilk in.

Flimsy and difficult to pour milk into. Never tried but nice that pumping directly into the bag is an option.

Easy to use start to finish
Sterile pouches that hold up to 6 ounces, easily lay flat to freeze. Label for date and time as well as amount and name. It’s nice to know exactly how much you’ll be thawing before removing from freezer! Compact size, easy to take on the go with lay flat to freeze feature!

Reliable
I really like these Lansinoh breastmilk storage bags and use them regularly. The material feels thick and durable, with no strong odor, and I’ve never had issues with leaking. The double zipper seals well and keeps milk secure in the fridge or freezer. My only downside is that when the bags are very full, they can be a little hard to get to stand up on their own. Other than that, they’re reliable and convenient for storing breastmilk. The appearance is also great.
