Review on AZFUNN Electric Beverage Mug Cooling & Cup Cooler for Office Home Desk Use - Aluminum Mug, Beverage Cooler Plate Accessories for Water, Milk, Wine, Cola, Beer, Cans - Travel-Friendly Beverage Cooling Solution by Justin Reese

**3. Update** - 05/24/2021 - Both of my coolers didn't cool very well. It turned out that the fans were almost completely clogged. After disassembly and cleaning, one works like new, the other doesn't cool at all, so I ordered a replacement. Like computer fans, they should be cleaned regularly with a can of compressed air. The one that is no longer cooling has been used EVERY DAY for 6-14 hours since purchase on 11/2019. Very happy with it. :) **2. Update** - I haven't worked since the purchase on 11/2019 due to an injury. The first one started making noise when I turned it on so I put it in the living room as I rarely go there. The noise disappears after a few seconds. The second works 14-16 hours, 7 days a week for several months. I am very happy with this little cooler! **UPDATE** Was on and working when I decided to move to another room. The power supply is hot, so make sure nothing is touching the power supply. AMAZING gadget! Keeps cold drinks cool. The aluminum cup is so cold that condensation forms on it. Fill a very small amount of water into the main unit, and then install the aluminum cup. This will help transfer the coldness into the cup. A 20 ounce plastic bottle is not suitable. I buy canned soda so that's not a problem for me. In any case, a beverage can made of aluminum stays colder than one made of plastic.
