I hate these bags. 1. They are very difficult to open. 2. The have lots of extra plastic at the opening, which makes pouring in milk from a pump difficult, and has resulted in spillage more than once. 3. They will not stand up, regardless of volume. 4. The labels are upside down. 5. The bags DO have an excellent seal on them, though, which is why they have 2 stars instead of 1.

These bags are really sturdy and freeze flat. I've purchased other brands where the corners have been sharp and would rip though the gallon freezer bag I store them in but these don't do that and are great! I've purchased at least 30 boxes of these so far and will keep repurchasing :)

You want to be incredibly careful with these. They are very thin and flimsy. When defrosting they WILL leak. It’s best to thaw in a bowl to catch. They freeze flat which is nice but not worth it when it leaks. Parents Choice bags are a far better alternative to these . Medela and Parents Choice bags have been my favorite .

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.

Out of at least 10 100ct boxes of these, I’ve only had one that was torn, and even that tear was at the top of the bag so I didn’t lose any milk transferring to a new one. I don’t trust any other brand! The only negative thing I have to say is that there is some inconsistency in the boxes. Some boxes have bags that are noticeably thinner than others, but they are still sturdy enough to keep from tearing or leaking. It hasn’t caused issues, but did make me worry a bit when I noticed it. I’m still giving five stars because even the thinner bags work great.

Great bags and good price

I need to leave this review … i thought they were the best but I have lossss a lot of my breast milk cause when they defrost they leaked. 😞

Quick shipping and good price. Love these storage bags. I used them with my last two little ones. Easy to write on and store in the freezer. Also easy to thaw.

I chose the Lansinoh pump and bags because you can pump directlybinto the bags and it is less dishes to wash. Have not had any issues with these bags leaking.
