Medela Breast Milk Cooler and Transport Set, 5 ounce Bottles with Lids, Contoured Ice Pack, Cooler Carrier Bag

Needed this badly so I wouldn’t have to buy formula for my 2 month old, it’s hard to breast feed sometimes when you’re so busy! This solved that problem, I can conveniently travel with my milk and have a bottle ready to go anywhere! So convenient and helpful for a busy mom of 2

Holds just the right amount for my supply during work. Stays cool and is perfect size!

I loved this cooler so much when I first bought it two months ago that I bought another one immediately. Now that I have been using it every day for these two plus months it is time to write a review. The size is nice and compact, it fits 4 medela brand bottles (5oz size only, the 8oz bottle does NOT fit in this cooler) without the teats attached ( I have had success placing 2 bottles with their teats but the zipper feels like it might break). I mostly use the cooler at home (as I am an exclusive pumper) - I only give my 7 month old freshly expressed BM and since the weather has been turning warmer I prefer to keep the milk in the cooler than on the counter. I do not keep it in the fridge as I do not like warming it up again for a feed- the temperature in the cooler is not cold enough for the fat to curdle and my baby accepts it straight from the cooler so its less work for me. Now that the weather is constantly in the 90s, I find that this cooler only stays cool enough for around 6 hours. I bought extras of the blue block and have to replace it around the clock. I do not know how long it will last if placed in a car in the hot sun for instance. The block also sweats (condensation) and is constantly wet. I wish they would make the bag a little large in order to accommodate bottles with their collars and teats attached but otherwise this product is really handy and works well for us.

The bag and ice pack are wonderful. One of the bottles numbers rubbed off. I’m not sure when it happened as all have been hand washed and never put in the dishwasher. Other than that, it’s great.

This worked just fine, but it was a bit square when it came to putting it into something else to take to and from work while pumping.

Easy to use! A must have for any pumping mama!

Like many of the other reviews, two out of the four bottles that came with cooler set warped in the microwaveable sanitizer. I will still use this cooler because it is compact and fits Medela four bottles which is enough for an eight hour work day for me (I pump every 3 hours and the last pump is during my drive home). The ice pack is also large enough to keep the bottles cool, although I haven’t timed how long because I have access to a fridge at work.

I really like this cooler--it is compact and perfectly holds the four medela bottles and ice pack. The design ensures all four bottles stay cool and in touch with the ice pack. I would have given this five stars, except that one of the lids for one of the bottles was defective. As a result, I lost 2 ounces of milk on my way home from a business trip. I assumed I must have not closed it properly, but then I lost another ounce the next week somewhere along the journey between my office and home. I tested the bottle and lid out with other bottles and lids, and was clearly able to tell there was a problem with the one lid. While I didnt cry over the spilled milk, it was very disappointing. You go through so much to do it right, to lose three ounces due to lid defect is upsetting.

Short n sweet: This cooler was made for and perfectly holds 4 five ounce bottles and a bottle ice pack. Keeps my milk cold all day until I get home from work to throw them in the fridge! Update: I’ve had my Medela cooler pack for a little under two months at this point. I’m still completely satisfied with its ability to keep my four bottles cold throughout the work day. I am however, disappointed by the mediocre quality of the zipper pulls. One of mine has now detached rendering one of the two zippers useless. This was after use of the cooler only three times a week. Unsure if this is typical versus an isolated issue.

I originally purchased for a flight that I ended up canceling. I was going to try to store frozen milk in bags. I dont believe I would have been able to fit more than 20 oz of frozen milk. For this use I would have been better served with a regular lunchbox which was cheaper, but I needed more containers and kids (which are expensive!) so I opted for this instead. It does exactly as advertised. Would prefer more ice packs on the side for longer trips (like ameda bag), but for daily pumping needs this does the trick. If you pump more than 20 oz a day, consider ameda bag which fits six bottles.
