I have used this six or seven times in the three months I've had it. Love it. It hold plenty for two people for two or thee days. I pre-chill beverages the night before, then throw a frozen water bottle in there. Very good insulation as the frozen water bottle keeps things at my 38 degree set temp for a very long time. I then hook this up to my solar 12V at cabin. Uses around 35 watts when compressor is running.
