The Mobicool G30 has fully met my expectations. After reading other reviews, both for this and for other coolers, I knew what I could expect. Therefore, I was not disappointed that the power controller for the 230 V - is operating, and in that one in 230 V - (barely audible fan from 3 m distance) creates fashion no more than 8 K temperature difference - Eco. If that's not enough, you need a fridge, or even much more money needs to invest a part of that! (In maximum mode I reached up to 14 K). The noise in maximum mode, I find not so disturbing as others have shown it. Previously I had a non-adjustable GIO style - cool box, and it was really loud. Thus, all in all an entirely positive impression! I can recommend buying.
