I purchased these to use with my daughter who is 3 1/2 weeks old. I was skeptical because of the reviewers that had issues with leaking but I have had great luck with these - no leaks whatsoever! I make sure to get all the air out and I've stored them upright and flat (although flat is easier with the space I have). I've even dropped a couple of bags with frozen milk on the floor and haven't had any issues with leaking. I've used 2 1/2 boxes so far and haven't had any issues. I would highly recommend this product!

Ive tried all the other bags but these are by far the best! No leaks and its easy to pour the milk from the bag to the bottle without spilling!

I used a 50 count bag and had good luck at first. I hadn't been smart enough to store frozen flat...sothat might have been part of my problem. Although, I did find that the longer something was frozen the more likely it was to leak. I ended up thawing in a ziploc bag most of the time just to be safest.

For the past 9 months: I thaw approx 15 bags a week, store a minimum of 55 ounces a week, and keep a minimum of 600 ounces in a deep freezer at any time. This comes to roughly 900+ bags used in 9 months. Never had a leak. I'm very happy with the Lansinoh storage bags.

Keeping a smaller amount of milk in each bag (2 or 3 ounces instead of 6+) is a good idea because milk expands in the freezer. Recently I have begun to store 5 and 6 ounces at once to see if these bags would have a problem. The larger bags also have not leaked, but I wouldn't recommend putting more than 5 ounces in any bag if you are very concerned with losing milk.

The double zippers have a great seal, and the writing area is a good size. Freezing these bags flat and then sticking them inside a larger freezer bag has helped to keep milk fresh. Also, never had a freezer burn problems with the bags that were not stored inside of a larger freezer bag.

I have been storing away a lot of milk for when I go back to work and I wanted to c heck on how well my milk froze. So I defrosted a 4 oz bag of milk that I stored 6 weeks prior only to find it had soured. I then defrosted multiple bags of milk and found out that over half of them had holes in the bag which caused my milk to sour! I am so upset that I had to throw away over 20 ounces of milk! I now am double bagging my milk and putting them in freezer bags... hopefully this works.

I have been using these bags for the past three months. They're very easy to use and I love that they have the double closure. I usually fill them with 3-4 oz. and then squeeze out all the air before I freeze them. I freeze them flat and then place them all in a plastic bin with the oldest in front so that I make sure they're rotated. When I thaw them, I place them flat on a large plate in case one of the bags leaks (which they never have) and leave it in the fridge overnight. They're thawed enough in the morning to pour the milk into bottles for daycare. I have never noticed freezerburn and my daughter has never refused to drink the milk so I'm sure it's okay.

I have tried the Medela that work with my pump and keep going back to the Lansinoh bags. Even though the Medela were convenient and eliminated the step of transferring milk from bottle to storage bag, the Medela bags were much stiffer and harder to store. They took up way too much room in my freezer since you have to store them standing up. I would definitely recommend the Lansinoh bags to any working mom who has to pump every day. I've used over 200 bags already and never had a single leak!

These bags work pretty good. I like the double zipper. They freeze well flat. I have had 1 bag leak while thawing, but I was able to salvage the milk. My only real complaint is that the "pour spouts" don't stay sealed on the majority of the bags(I think only 2 or 3 out of 50), but they are still relatively easy to pour.

These are a better price than the Medela bags and freeze flat while the Medela do not. I have had a few leak when I am thawing them but it is not that big of a deal. I'd say they are the best deal. If you pump into bottles though and just bring those same bottles to daycare the next day you won't need that many of these (I think I bought about 400 and won't end up needing near that many)

I bought this storage bag thinking that I would go mid level in price, thinking I would get a good product. These were the worst bags!! I had to go back to work and am pumping, which is hard enough without lossing half your milk because the bag leaks. I had 3 bags leak on me while I was pouring the pumped milk in. After I had the first one leak I thought well maybe it was just a bad bag, but 3 bags. I never even got to the freezing part to experiance the leaking on that end. I have used both the Gerber and Medela bags and I can say that I have never had a bag leak from either one. I will never buy these bags again.

The bags are great because they have the double zipper so you don't have to worry about the bags leaking. They are large bags that hold up to 6 oz. of milk. They are easy to pour milk out and are cheaper than other storage bags.
