Used this brand exclusively two years ago and loved the quality and how they were able to stand on their own. The new design to the bottom of the bag is so narrow and bad they are not able to stand own their own anymore. Have to look for a new brand to use now.

I have used these bags during two exclusively pumping journeys. they freeze flat and when filling them to 4oz, laying flat in the freezer, i can make a brick of 13 bags/ 52oz. i am a massive over supplier of over 100oz DAILY. So i go through a ton of bags. these have always been my favorite

We like these bags as they don’t damage easily. We tried others and when defrosting the milk it had holes in the bags and the milk leaked everywhere (super upsetting) and we haven’t had that happened with these. Only negative we have is they are not as easy to pour the milk out when trying to pour directly into a bottle.

As an exclusive pumper with our first baby, I had no problems with these bags and they worked great! I’m an exclusive pumper again with our second baby (only 15 months apart) and this time around I have had many bags leak when thawing them to make a bottle. It is incredibly disheartening to see all of my hard work go to waste, especially when I see it’s a bag from my middle of the night pump. I’m not sure what could have changed so much from last year to this year with the quality, but I unfortunately won’t be using them again.

I like that you can pump directly into the bags and Walmart does a great job of getting them to you quickly if shipping. What I do not like is that there are two types: ones that are a little thicker and ones that are a little thinner. The thinner ones very frequently have micro holes, so they leak. Unfortunately, you cannot tell what you are getting until you open the box.

These work okay, unfortunately the last time I purchased I got a few leaky bags that weren't able to tolerate the freezer. But I like the size of these, I can easily put in over my flanges without needing an adapter. However if you're transferring or by chance leave it on the counter for a second without sealing it there's a good chance it will fall over. I've lost quite a bit of milk this way.

We've been using the Lasinoh storage bags for about 6 months. For the most part they work great, but we have had a few problems with a few of the bags leaking. You can tell it is a problem with the bag and not a closing or seal problem. We have tried other brands and this brand does not work any better or worse than others.

A good portion of the bags leaked. They also were sealed at the top it rarley tore at the dotted line making me cut the top off of almost all of them just so i could get it open. Dont want to buy again and waste all the milk and money so I am goinh ti be trying the medela storage bags.

I use these bags to hold pumped breastmilk in the freezer. I have not had any problems with the bags' integrity holding up to various temperature conditions. I don’t, however, defrost the milk in the microwave, which is not recommended anyway (creates hot spots in milk), so I wouldn’t know how well the bags would do in that situation. I've only held frozen milk in these bags for about a month at a time before I would need to make a bottle for hubby to feed the baby. Breast milk can be frozen for up to 6 months, so I would need to do an experiment to see how well the bags holds up. My only concern is when pouring the milk from the bag into a bottle, I need to be careful of where the milk touches the non-sanitized part of the bag's opening. I tend to wash the opening flaps first before opening the bag. Lastly, knowing how much milk is being stored in the bag is better determined by a baby's bottle set on an even flat surface. The level read on the bottle is always different than the level read on the bag.

I freeze two bags per day, and these are the best. Double zipper is great, but the best aspect is the shape. They don't stand on their own, but I know no mommas who would trust their milk to a self standing bag anyway! The shape is perfect to freeze flat for evenly shaped milk. I tried the fancy pump-brand bags, but I always return to these. Great gift, btw. Love them!
