GROWNSY Portable Bottle Cooling Device w/ Digital Lid, Green Ready In 3 Minutes

There are some scuffs on the lid, but everything works as it should. Portable Baby Formula Bottle Maker with rapid 3 minute cooling. This system is really interesting. I tested it with hot water from my kettle. There is a sensor in the lid. When you shake the contents or turn it upside down it senses the temperature of the liquid inside. If the indicator turns red it is way too hot. Yellow means it's almost ready, but not ready yet, and green means the temperature is ready to feed. Always check the temp yourself before feeding to baby. This also comes with a formula container and tea strainer for portable convienience. I was pretty shocked at how fast it cooled the liquid inside. No power needed.
