Rated 2 out of 5★ by tanayar Not all I expect from a storage bag.... This bag is great for the convenience if you forget a bottle at home but for me it ends there. Do to the shape of the bag you have to be extra careful not to overfill the bag even a little bit otherwise when you go to seal it closed you will end up with milk pouring out. The 5 ounce size is not large enough if you produce a lot of milk like myself. There are times I can get out 4-5oz from one breast so it is time consuming when I have to stop and put on a new bag when I am on my 15 minute break at work. They also only have one zipper which I do not care for. The other bags I use have two and prevent leaks. I was rushed and did not get the entire zipper zipped so when I placed this in the freezer laying down (I like to freeze mine flat to save freezer space) milk poured out everywhere. They are too pricey to not be very efficient. I will stick to my Lansinoh bags and leave a bottle at work just in case I ever forget one again. 11/12/2013
Rated 1 out of 5★ by 2Tull Does not compare to others While these are heavy duty they are small, I've found you can't put more than 4 oz in the bag if you go much more than that you can't get the air out without spilling half of the milk. These do not freeze very flat because they are so small. I much prefer other brands to these pricey ones. 03/18/2014
