Complimentary Freezable 12 Ounce Inner Chamber

The idea is good but the construction is terrible. The metal insert continues to warp despite following their instructions about how to freeze it.

I saw the new inner chamber advertised and was really excited because I’m an OG ceres chill user and my inner chamber was rounded at the bottom because I freeze it. I’m using my ceres chill again for my newest baby and thought a new inner chamber that could stand on a flat bottom would be great. From my understanding, the metal on the new chamber is thick enough to prevent bulging when filled and frozen. My very first use when freezing, the bottom of the chamber ended up bulging out. It will stand, but is wobbly and crooked. I was so disappointed because this doesn’t really fully solve the issue I have with my original chamber bulging and being unable to stand! I am grateful to the brand for allowing OG users like myself to receive the new inner chamber at shipping cost only, but shipping was around $12 which I probably would have chosen to save if I knew the new chamber would also bulge out.

Updating to 5 stars ! As an exclusive pumper for two kids now, I've been using the Ceres OG Chiller since my first kid in 2023 and now again since April 2025 with my second. I always use the inner chamber filled w ice, so was thrilled to see a freezable option now existed! After some initial issues with pumped milk in the outer chamber mixing with the frozen inner chamber causing it to melt, it turned out the issue was using old upper parts that were in need of replacement. The Ceres family customer service was exceptional - they immediately identified the issue and sent out newer, replacement parts which instantly fixed the issue. I will continue to recommend the ceres line of products to all lactating moms I know!

Great product. So convenient to be able to just put this in the freezer vs filling with ice and water.
No leaking. Would definitely recommend

Helps so much to just have it in the freezer ready to go. wish i had for the mini as well!!!

This inner chamber makes the Ceres chill even better (if that's possible!). It just makes you have so much more flexibility and makes the chill the best product out there for breastfeeding mamas. I love it! It was especially a life saver when our ice machine on our fridge broke 😅

This has been an absolute game changer for bébé #2. Being able to pop it in any freezer: mine, hotel room’s, hotel’s, friends’, etc. has made traveling so much easier!

This rocked and kept milk cold and safe during an outing to an amusement park and I didn't have to worry about replacing ice anytime which was amazing!!!!!

Complimentary Freezable 12 Ounce Inner Chamber

Love this product , perfect for night pumps i nonlikger have to walk to the fridge ti store my milk this keeps it cold for 12 hrs minimum

Love the new freezable inner bottle! It’s been very convenient to just pop in the freezer the night before and have ready to go in the morning.

I am a mom of twins and recently returned to work. The Ceres Chiller has been a game changer for my breastfeeding journey. It keeps the milk cold and is easy to travel with. The freezable inner chamber has been great! Fill with water, put in the fridge and you get consistently cold milk all day without having to worry about refilling the inner chamber with ice. If you are a new breastfeeding mom, do yourself a favor and get this!

Love that I can rely on this to keep my milk cold!

I love my Ceres Chill!! It’s amazing, I use it everyday to bring my pumped milk home from work. I love that they made the freezable 12oz chamber available for free. It keeps my milk super cold and safe!

I have an older Ceres chiller and reached out to update my inner chamber to allow the option of freezing the inner chamber. This has given me peace of mind with my return to work and continuing my pumping journey so my son can continue to receive breastmilk.

I’m a planner so I love the flexibility of being able to freeze the inner chamber beforehand planned outings or adding ice for last minute outings keeping my pumped milk cold and safe on the go.

This has been so helpful for trips and work. To be able to freeze the inner chamber and not worry about my milk staying cold is such a load off my mind!

I use the big chamber for milk when I pump at work, and filling the inner chamber with ice cubes was kind of a hassle. It's so easy to just fill it with water and freeze overnight! So glad Ceres came up with a way to accommodate this upgrade! I've been using it for a couple weeks now -- no bottoming out, and it keeps everything cold all day until I get home again.

What a life saver. Sturdy, shows you on the outside the max for water. It's made such a difference in my pumping journey.

Love it ! No more bottom blow outs from freezing

I can’t thank customer service enough for letting me know that this existed. Due to some unforeseen circumstances at work, my inner chamber got destroyed. I was able to buy all the parts I needed, and it came super fast and was able to continue my pumping journey. This is exactly the support I needed!!! I can’t thank you guys enough for helping me be able to feed my baby while being in the military.

This product is great! Allows me to keep large amount of milk cool in my og chiller. Great addition! Thank you so much

This is my second baby I am using my ceres chill for. It stores my milk and keeps it cold on long 10 hour shifts. They have amazing customer service and even sent an updated chamber so I could freeze it without issue for those extra long days. I recommend their product to all my expecting friends!

The freezable chamber keeps ice longer than the original. I love this change!

I was just telling my husband how they should come up with a way to freeze the inner chamber and then I saw it online!

I gave it a 4 because I used it correctly, yet the bottom already popped out in the freezer so it’s no longer flat. I will contact CC for a replacement.

I’m so amazed at this chiller! We aren’t allowed to bring glass bottles to our daycare so this chiller has flexed as a bottle. Thank you for making a great product that gives parents an option to use dr browns standard nipple with a stainless steel bottle!

This is a hands town must have for traveling with a bottle fed baby.

Lisa is the most generous person out there! This update is a game changer!!! Dont bother with the copy cat chillers out there by momcozy, boon, willow… get the OG; Ceres Chill!!!
