An extremely good product. Very fast to cool down from 25C to -10C in aprox 20 minutes. Furthermore the compressor is very silent and with no annoying compressor sound as you might experience with portable countertop ice cube makers. This device has a DC compressor and is much more silent than an AC compressor. The operator display and BT app works also very good and stable and is good quality. So please do not buy a cheaper Termo Electric Cooler(peltier element) for saving EUR 50 -100. This product works outside, in sunshine etc with a fast cool-down time, so I can only recommend this product.
