The new design seems cheaper than the old. The perforation at the bags opening is flimsy and results in ripping the top of the bag when you go to pull off the seal (this never happened with the old design). Also the new bags do not sit vertically as easily when you pour milk in. I was used to the old bags which sit easily on my counter as I pour and with the new bag, it immoderately toppled over as I started pouring and in early lost 5oz!
I’m thinking lansinoh wanted to save money with the new design but have now put out a crappier product.

New design loses some ease of use

New breastmilk storage bags
We all know the feeling of spilling even a drop of milk. These new storage bags have spilled my milk twice from a hole at the side of the bags. I literally shes a tear as almost 2 ounces of milk spilled and I didn’t notice it. It’s too plasticy for me. I prefer the old bag way better.

Wanted to love but not the case
I bought these a week ago and I have already had milk spill 3 times they do not hold up for a second. It’s truly annoying

New Design Has Flaws
I LOVED the ones with the blue zipper (I believe that’s the OG design). I recently ordered more and got the new design with the pink zipper and the big Lansinoh logo flower on the center of the bag. This zipper leaks before I even get my milk in the freezer! I wish you’d go back to the stronger zipper if you’re going to change the style of the bag.

Terrible
They’re hard to pour milk into. They don’t stand. One fell out of my fridge due to not being able to stand and got a hole. Thawed a bag of milk and it started leaking.

Favorite and Most Durable Storage Bag
I have used this brand for my breastmilk storage for YEAAARSS. Never have I had an issue with spilled milk or nothing. I’ve kept my breastmilk for up to a year, that I had saved for breastmilk baths for my kids and the bags condition was still excellent. Definitely helps with keeping your milk flat and having enough storage.

The flatest bags to freeze!
I love making frozen milk bricks from these brags, they are the flattest! They make the perfect frozen bricks for deep freezer storage. By far my favorite and they don’t leak!!

NO LEAKS!!
I bought these during pregnancy and so far (3 months in) they are the only bag that hasn’t leaked when thawing! I typically freeze 4-6oz depending and have had absolutely no issues, plus they fit great in my freezer storage container!
