Great size. These bags need a pour spout like the Ameda bags. It's not easy to pour milk from the bag. I've wasted so much milk trying to pour milk into my baby's bottle. I will be going back to Ameda bags. They're a little pricey than Lansinoh, but they are worth it.

When I sat some on the counter to thaw, some of these bags had tiny holes/tears and I lost the milk. I had them stored in the box until use and they were in a separate container in the fridge, so they shouldn't have gotten damaged from how I stored them. 90% were fine but I wont take a chance and use these anymore.

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!

I store more than the 6 ounces it says to, and they still work great! They obviously take longer to thaw, but that's no big deal! I've stored at most 9 ounces but have been storing at most 8.5 ounces per bag trying to stick with just 8 unless there is only half an ounce left over.

I've purchased and repurchased these bags only to find out they aren't the best. As I needed to start using the milk, I would noticed that a lot of the bags would leak as they would thaw out. That is so frustrating to see the wasted milk. Completely disappointed in this product, definitely wouldn't/didn't repurchase.

I used these storage bags for breastmilk with my last two babies. The bags are not flimsy and are stand up to use. They work OK with my breast pump. They seal well and the measurements are easy to read. I have also placed these bags in a larger freezer storage bag for future needs.

I’d give zero stars if I could. I’m so frustrated with these milk storage bags as they continue to all leak. I’ve just started to thaw out the freezer milk since returning back to work from maternity leave and almost every one that I’ve thawed out has leaked everywhere like this! I have worked too hard trying to save a good freezer full of milk, now SO much has gone to waste.

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 love this product because it makes storing breast milk so much easier. it is space saving in the freezer than trying to find bottles that don't take up a bunch of space. seals great and you can record the time date and everything on the bags when you pump.

Theyre my go to breastmilk storage bag. The seal is tight. No leaks. The only issue is dont trust the measurements on the bag, measure the milk before pouring it in because its not accurate but thats with any milk storage bag. This brand claims it only holds 6 oz but i managed to fill it with 10 oz. Even with 10 oz there was still room and the bag held up after freezing.
