Product review (3 stars): Nostalgic soda vending machine
This nostalgic soda vending machine uses a Peltier junction for its cooling; it does NOT use a conventional refrigeration system, with a compressor and pump.  There is NO temperature adjustment option.  The cooling is adequate, but if you like your sodas just above freezing, this cooler is not for you.  The coldest interior temperature my unit can achieve in a 72F ambient room is 36F.  Adequate ventilation at the rear of the unit is a MUST.

The 60-watt power draw claim in the manual is wishful thinking; my digital wattmeter says it's more like 73 watts.

The unit uses a 120 mm (5 inch) 12-volt fan directly over the heat sink with the Peltier junction device.  This fan is critical to the proper operation of the Peltier junction.  I had the fan on my unit fail after about 9 months (well past the underwhelming 90 day warranty).  The fan makes little noise, so when it failed I didn't notice this until I dispensed a soda and found it quite WARM.  The Peltier junction heat sink (it's quite substantial) and power supply circuit board providing 12 V DC to the Peltier junction were almost too hot to touch.  Fortunately, replacing the fan wasn't difficult (I found a replacement from Cyberguys.com, costing $12), and once the circuit board and Peltier junction cooled down, and with the new fan, everything seemed to be okay again.

The dispensing system uses a mechanical push stop linkage that holds the soda can in place until dispensed; it's a simple system that works well.  Restocking the vending compartment is also simple- just open the door, and you have easy access.

This unit has been a nice addition to my office, and it's certainly convenient to be able to dispense a nice cool (but not ice cold) can of soda when desired.  But had I not been an electrical engineer able to replace the fan when it died, this unit probably would not have been cost effective to send back to the manufacturer for a non-warranty repair.
