Love it! Our first one stopped working after a few weeks of minimal use and Kiinde replaced it right away we have to thaw out breastmilk from time to time and it works very well!
This warmer is very sensitive and you have to clean it all the time or else it breaks. But the warmer works great if you take care of it and clean it often.
I’m actually a little bummed. I originally bought my kozii in January and loved it!!! Then all of a sudden it stopped filling up with water. Then Kiinde replaced it, which was amazing!!! But the replacement stopped working. ALREADY! It has only been a couple weeks since we got our replacement. I really want it to work since it worked so well for us for the first few months we had it.
