How do you use the warmer function?
Best Answer: To use the warmer function on the Ceres Chill OG+ Chiller/Warmer, you fill the outer chamber with hot water, then place the cold milk or bottle in the inner chamber and seal the unit; the hot water in the outer chamber gently warms the milk in the inner chamber so it’s ready to feed after several minutes. Avoid using boiling water or extremely hot liquids, and give it a bit of time for the heat to transfer evenly.
hi I see how it works as a chiller how does it work as a warmer?

This bottle is such a fantastic invention
This bottle is such a fantastic invention. Not having to remember to place ice packs in the freezer the night after a terrible shift is a blessing! You are able to just grab your bottle and go in the morning, ready for another crazy shift! The quality is awesome, and it really keeps milk cool for your whole long shift and more! Easy to clean, easy to set up. This will be me baby shower gift for all my future pregnant besties from now on.

The best!!!
I bought the gift bundle with custom engraving for myself as a going back to work gift and I am SO glad I did! The design is sleek and extremely well-thought, easy to clean, and keeps milk cold all day. I love bringing just one thing to store and chill--so much more efficient! And I can't say enough good things about their customer service! 10/10 recommend!

One of the best baby purchases I’ve made
This chiller is seriously amazing. I freeze the inner chamber and it keeps my milk cold all day, even on 14+ hour shifts. It gives me the peace of mind I need to focus on other things because I don’t have to worry about my milk. I got the white chiller and decorated it with black cow spots which just makes it more fun (:

If you’re on the fence, don’t be! You won’t regret!
If you’re on the fence, don’t be! I left mine open overnight and there was still ice in it in the morning! You’ll use it after your done with your breastfeeding journey, too. I’ve been done breastfeeding for about 2 years. Now, we pack popsicles for the pool or lake! Great for camping too with a built in cup. I can’t say enough great things. Best investment ever!

Disappointing
This does not keep milk at a safe temperature. The only time I was successful was putting milk in the outer part and turning the whole thing upside down so that milk actually comes in contact with the center ice container. Then when I add warm milk to it from the second pump of the day it never gets back down to a safe temperature. I only add one additional pump session and it can’t handle that. I have tried to troubleshoot in all the ways I can think of. Very disappointed…

Very bulky and difficult to pour into bottles. Difficult to clean - especially the silicone rings inside the lid.

The Best Chiller!
I’m a first time mom and mother-baby nurse who just went back to work 2 weeks ago. I’ve been using my chiller ever since I started back, and I love it! It is so easy to use and keeps my breastmilk cold my entire 12-hour shift. I will definitely buy more Ceres Chill products and highly recommend to others!

MVP of the pumping journey
I have 2 of the original chillers and have upgraded to add the freezing inner chamber (OG+). I love having the flexibility to freeze or use ice because I will definitely forget to freeze it at some point, but I can always get ice. I pumped for 18 months with my first kid and never worried I would forget my milk at work or someone would mess with it because I had it with me the whole time. Two chillers allowed me to prep for the next day and then wash the used one when I had time (or my husband…

OG+ Chiller/Warmer
I purchased a chiller/warmer for myself, and now, as more of my friends are having babies it's the perfect gift. The OG+ Chiller/Warmer just makes life easier. It's so much better than having to cool down milk on ice before putting it in the fridge. It's now my go to baby shower gift because people don't think enough about moms!
