I have three different milk, coolers, and the one that I grabbed the most often… momcozys.
In fact, the only time I grab the other ones is if I can’t find my Momcozy one for some reason or I happen to need more than one like I’m traveling with a lot of milk.
Momcozy - top pick - handle , keeps cold, can be used with ice or ice packs
Baby brezza- pretty white and handle but the ice packs go above the stainless steel so the top part of milk gets warmer than the rest!
Ceres chiller- no ice packs and instead use ice. But I hate the thought of pouring milk straight in because big thermos are so hard to air dry so then I either have to hand dry the entire inside by getting my hands stuck in there, or I have to be worried that the residual water sat too long.
