At first I tried the containers in addition to the bags. I soon found that the containers were bulkier, messier, and harder to clean. So I gave those away and stuck with the bags. They work well but they are so expensive for plastic bags. Wish there was another way to open them besides cutting with scissors. Also wish they came in larger volume options - say 6 ounce, for those of us who like to wear the bags hanging out of the flange rather than tucked inside.

These bags are wonderful. They make it easy to pump on the way to work without having to worry about spilling milk. I totally recommend the bags!

Convenient for on the go but a little expensive

If it wasn’t for the coupons I would probably not buy them. They are pricey and I have had a few come defective. During a session the pump doesn’t work, but then on another session using a new bag the pump works perfectly. Overall I am very happy with the product.

I started with the spill proof bags. They worked well but thought I would save money by using the reusable milk containers to pump directly into. When using those, pump constantly malfunctioned and asked me to flush water through, blah blah. I couldn’t take it anymore so I went back to the bags. They always work with the bags. On another note, this pump costs way too much to ever malfunction like that. Also, it hurts terribly. I bought different size flanges and it still hurts. To the point I am bleeding and actually found a blood clot in my pump on two separate occasions. Lactation specialist said she hears this a lot with wearable pumps. I wish I had known and never bought these.
