To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
I have used Ameda, Medela and Lansinoh bags recently, and figured I would post a comparison of the 3.
Ameda: Love the pour spout, but haven't really had a spill issue with any of the other bags so it's more of a nice to have than a must have. Good, thick plastic, and bags stand up on their own quite well. Zipper seems secure, although sometimes its hard to tell if it's closed. Has the smallest zipper of the 3 bags. Also, very disappointed that this listing was for the bags only, and did not include the adapters to pump directly into the bags. Luckily, with a little finagling, I was able to use these bags with the Medela adapters.
Medela: Similar to Ameda in plastic thickness and design. Also stands up on own easily. Zipper seems a bit more reliable than Ameda. I liked that the adapters were included in the box and these are easy to pump into.
Lansinoh: The thinnest plastic of the 3, and don't really stand up on own easily. These have a double zipper though, which is great, and it's easy to tell when the zipper is closed. These also lie the flattest when frozen, making them the easiest for storing frozen milk. These are also by far the cheapest of the 3, usually costing around half of what the others do. However, these cannot be pumped directly in to.
Personally, I use the Lansinoh bags for whe I pump into bottles and then pour into bags for freezing. I use the Medela or Ameda ones when I want to pump directly into bags. In my opinion, they all stink as far as volume measurement, so if I need to know how much is in there, I usually pump into a bottle, measure based on the bottle reading, and then pour into the bag. Otherwise, when zipped, they usually read about 1 ounce more than what is actually in there.
These bags are durable, stand on its own, easy to pour into (from pump), and easy to pour out of (into bottle). The measurements are way off so make sure you’re aware of that and label the correct measurements. These bags only hold about 4oz btw, wish it came in more sizes but I’d buy again. Best bags I’ve used so far just because of pour spout. Lifesaver!
These are the only milk storage bags that I have found that you can both pump directly into and pour out of a handy tear-open pour spout on the side. This is great because its way easier to pour the milk out and more sanitary. The bad thing about them is that the measurements are very approximate (however it says this on the bags), especially if you have a small volume because the bottom part of the bag won't flare out with less than about 3 oz inside. Also the bags will stand on their own as well, given again that there is enough volume. One other little annoying thing that keeps these from being great is that they don't seal as well and as easily as I'd like. With a few improvents these would be awesome, but they fit my lifestyle well enough as-is, very convenient.
I have heard from friends about how much of a pain it is to find the perfect breast milk storage bags but to me it was simple. I bought these off of a friends recommendation and have loved them. They have not busted or spilled which I hear is a common mishap with storage bags. They are so easy to pour, that I have complete faith in my husband when he has to do it. The corner that you tear on the bag is a perfect tear too. We have never had to cut the corner with anything other than our hands. I have a medela pump so I actually pump into bottles and then just pour into the ameda bags. I highly recommend this item and I only wish medela would make bags like these easy to pour bags. I'm giving this item 4 stars because it can be a little hard squeezing all of the air out of the bag due to the size and limited headspace. Also, I wish this came in 6 oz as opposed to 5 oz. for those times you have just a little over 5 oz.
I have used these bags for about 8 months, and overall, I'm fairly satisfied with them, they freeze well and pour easily. There are a few drawbacks, however they can be overcome.
1 - the measurement lines on the bags are very inaccurate. To compensate, I measured out water and poured it into one bag, filling it as open as I would have it when pumping. I took a sharpie and labeled measurement lines on the bag with the measured water. I could then use this to compare to the bag of breastmilk to determine how much was in there. Before long I knew how much was in there without needing to compare. I would write this along with the date on the bag before laying flat for freezing.
2 - The ziploc is very tight. I don't see this so much as a drawback as something you just really need to be aware of when opening the bag initially. I would just make sure to pinch it a bit and open carefully from the center and I never had an issue with tearing the bag while opening.
These aside, the bags seal tightly and will lie pretty flat for storage. I have never had any issue with the bags leaking.
