Only that we find the gleichmal: The device is of Chinese origin, the United CASO is so pure eyewash. The idea would be not bad: always properly chilled wine at the table, the whole unobtrusive, elegant and quiet. Nix of the relay can. The volume is reminiscent of an over noisy fan (which is indeed final), the set temperature is reached the device - if at all - by the hour, as is the wine already no more talk. And an indication that the desired temperature is reached, is completely missing. The part is simply useless and on top of that for a fan with LED indication and power supply (which can not be switched off) completely overpriced. Steer clear of this unit. If I had not given it, I would throw it now heavier heart in the trash.
