I LOVE my ceres chill! It's amazing! It cuts down on the number of bottles I pump into which means less bottles to clean!! It fits into the mesh water bottle pocket on my pump bag. It keeps the milk cold all day and then some!! I'm a nurse and work 12 hour shifts and I don't have to worry if I forget to put my milk in the fridge during my shift or leave it out when I come home because it's still cold! So easy to clean. I'm thinking of getting another one my husband can use when he has the kids and the baby so he doesn't have to worry about a cooler bag, ice packs, and bottles. I wish I had this when I was in the military because nothing worse then worrying about how to keep your milk cold all day.
It's also durable as I've already dropped it and it didn't spill crack or leak any milk!
At the end of all I have to do is pour my mill onto bags to freeze! So easy!! And just clean my ceres chill!
