Overall I like these bags! I pump directly into them with their adapter piece and haven't had any issues with that. However, I have had a few days break or leak.

Easy to use. Cost effective. Even my husband can use them while I'm at work and he has to make the baby a bottle. No need to improve on anything with this product. Meet and exceeded my expectations. Definitely will be buying again.

These are a lifesaver. They're super durable and great for pumping. My suggestion is to label before you fill, lay the bags flat after you fill them, and then stack them like that in the freezer. These were great.

Used with both of my kids. Love these the most. They hold up well. No leaks so far and they’re the easiest to close and avoid liquid gold from going to waste.

These bags are worth every penny! They last in our deep freezer over 12 months and didn’t have any issues or concerns. The writing doesn’t smudge off.

Love this bag, I have never had a leak with these bags and I can fill it up to 190 ml no problem. It's double sealed and I can write the date and time at the top to keep organized. I'm currently using it and love it.

These bags have worked great for us. They freeze and defrost well, they don't leak, they lay flat and stack well. I like the measurements and the labeling options too.

These bags are very handy for pumping milk on the go I literally have them in my glove box with a manual pump and they are great for storing milk in the freezer.

These bags are easy to use and reliable. Other brands tend to tear easily. I can use these with my Lansinoh pump and the pump provided to me at work without difficulty. I will not use other brands. Thanks Lansinoh for making pumping easier.

I use these bags and usually buy in bulk. I have an oversupply so keeping these in stock in my house is priority. I love how thin the bags are, yet they are very durable. They have yet to leak on me!
