Only used one so far & it worked very well for me. I dont freeze milk often but these are great to have on hand if i need to.

These are my favorite breastmilk storage bags by far. They hold up really well and are the easiest to fill in my experience.

I've tried several milk storage bags. These are by far my favorite without having unnecessary bells and whistles.

Never had a problem with these leaking and love how it has the option to write date, time, and volume on the bag

I use these every day to store my breast milk. They don’t leak and are easy to store in the freezer.

These seal up very nicely. I have tried other brands but ways seem to go back to these. They hold up well in the freezer.

You cant go wrong with these strange bags. Easy to use by freezing and easy to unfreeze. The are easy to pour into and see the quantity you have.

These don't leak and can be propped up. I really like the double seal. Easy to heat up and pour milk from.

These bags are great. Never had any problems with leaks. They lay flat in the fridge/freezer so they don't take up too much space.

I actually prefer these over Medela. These would be my first choice. If these weren't on the shelves I would go with Medela.
