First the unit works extremely well. The current was measured at 5.56 AMPS at 11.98 volts the speed of refrigeration was as stated extremely good. This is to be used too cool my drinks as I do not like hot drinks at all and usually drink fruit juices. After first trial tried to fit the SPACE RETAINER However could not find a way of doing so. But on further thought found it and pictures enclosed to help those who like me went down wrong road. Extra long bolts are required to clamp it into place nuts and washers.. Other than that excalent piece of kit. The Spacer was alltogether in the same box so no need to buy extra. Peter

I tested this device with a power supply that only delivers 7 volts and 6 A, that is 42 wats. Nevertheless the result was better than expected. In a room temperature of 30 degrees I get 2.5 degrees in 10 minutes. With a laser infrarred thermometer I read -1.5 degrees inside the cooled aluminium radiator. I am sure I can get temperatures below 0 at 30 degrees room temperature with 60 wats. I never seen such a powerful peltier cooler. I think the cooper pipes can eliminate heat at very high rate, maybe there is some fluid inside the cooper pipes that evaporates. I don't know how it works but with only 40-60 wats you can get below 0 temperatures. Condensation of water starts inmediatly after pwering up the device.
