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

You just arrived. All were packed in a small box. None of these were broken, but they could probably have been packed a little better with a small piece of bubble wrap or styrofoam to keep the Peltier devices from moving around too much and to ensure they arrive intact. As I said, mine were fine. I just randomly tested 3 of these and they seem to be working fine. Great price for her. I'm looking forward to my project, I planned it!
