Review on 🌡️ GeeBat 10PCS TEC1-12706 Thermoelectric Cooler Heat Sink: Efficient Peltier Cooling Solution at 12V 5.8A by Justin Early

1. Received chips a few days late.2. All chips have been tested and all work perfectly.3. They say that there is no turning on and off as long as there is power. (I've bought Peltier ICs that turn on and off every few seconds.) 4. I haven't tested all of their temperatures yet, but the temperature difference seems to be 80 to 100 degrees Fahrenheit, cool/hot. (Later I will post additional test results such as: - Temperature readings over time, cold and hot. - Current draw 5. All chips were 1.5 inches. 6. All chips arrived in good condition, no chips , cracks 7. The packaging They arrived in sufficient quantity (bubble wrap, groups of 5 stapled together in a double bag, each piece correctly identified. Overall, I am satisfied with the quality of these chips. I have ordered many things made in China, the 3 showed or more defects of 10 pieces, so it can be said that I am also surprised.I would recommend them to the buyer based on this sample.As always, buyers beware!
