Review on Premium Coffee Mug Warmer for Desk with Heating Function - 25 Watt Electric Beverage Warmer, Adjustable Temperature (131℉/ 55℃ or 167℉/ 75℃) - Mug Not Included by Brian Sobirov

At the time of writing this article, the reviews for all mug warmers sold by Revain are mixed. I chose this one because I liked the auto shut off feature when you don't have a mug on the hot plate. I also found it more attractive than some of the other options. Wow! The thing does a great job! It keeps the tea warm all day long until vaping! I find that I use a thin, completely flat-bottomed cup, per the manufacturer's recommendation. Can only recommend this cup warmer!
