Delivery within a week in the carton with mention made in China. If a Danfoss? I have not removed the cover to see brand compressor but a small label * "Chinese design" * is visible through the shell grids If I put the cooler to the test on the day of the reception with 4 large bottles of water. Outside temperature 23 ° - 17 ° inside tank - 23 ° bottles. I set at -5 ° to 16.30. At 8:15 p.m. the tank is water at -5 ° to 11.7 °. I do not bother myself regulation time, but at 2:00 am, the tank is at -11 ° and 4.2 ° water. I set at -18 ° and the following days I found my 4 bottles in ice block but less rapidly than in my big freezer (I did not notice the time, a thousand excuses). The cooler has allowed me to empty my small freezer garage time to defrost and clean. Since I set the cooler to -3 ° with a water btl. Water is at the limit freeze, regulation raised over 2 hours at 17 ° exterior is 4.45 mn compressor to stop Operates in 44.30. The engine is quiet. The compressor output temperature during the first test was 40 °. Finally for now I do not regret my purchase but I would have liked more rsgts product (especially compressor brand manufacture origin, etc)
