Review on 🌬️ Efficient Cooling Solution: Northbear Thermoelectric Peltier Refrigeration Heatsink by Michael Patilla

This is the second thermoelectric unit I have installed in my refrigerators. So far I like this one better than the first. As others have said, this doesn't freeze the contents of the fridge, but it does extend the time that pre-chilled food stays cold and keeps the temperature around 30-40 degrees cooler than ambient.
