Before bed last night I put it on the coldest setting and woke up to find the cup of water frozen solid. I won't be using the freezer to freeze things very often, as most items will already be frozen prior to putting them in there, but it is nice to know this thing works great and will freeze food if needed. The compressor only kicks on every 30 minutes or so unless the lid is opened, so it maintains temps very well inside. I was also reading the owner's manual to find out it has a built-in low voltage cut-out and will switch off at 10.4 volts to save the battery. So at this point I'm thinking the $106 I paid for this is money very well spent. I'm not sure what other freezers on the market in the 45qt size come with a Danfoss compressor and a low voltage setting, but it seems most are over $600. And even better, one of the baskets I picked up fits the bottom and another fits the top perfectly. I'm going to unplug it with the ice block and some ice cubes in a small bowl in there to see how it does overnight with the lid closed.
