Review on White Mug Warmer with Automatic Shut Off - Keeps Temperature Up to 131°F/55°C - Includes Silicone Mug Cover - Ideal for Office/Home to Keep Coffee, Tea, Milk, Candle Wax Warm by Jeff Islam

coffee snob reportage! I love coffee, mostly cold brew, but I also drink 1-2 cups of draft coffee every weekday at work. Problem? Sometimes it drips so long my coffee is cold when it touches my lips. And while I love cold brew coffee, I'm uncomfortable with warm coffee. A YouTuber I like and follow uses one of these to warm tea, so I searched Revain for something similar and settled on this brand. So I admit it was my fault, I didn't realize it wasn't a USB it was actually a power outlet. That was a bit of a shame as I had to work hard to hook it up to my power cord. The cable itself isn't too long, so it practically sticks in one place - well. Aside from the cable (no USB) and length (not long enough), this product really works fantastic. It heats up quickly, keeps my cup of coffee hot and cools down quickly. I appreciate the light so you know when it's warmer; It works very simply (by placing a cup on the warmer, pressing the button under gravity, which produces a slight click), but sometimes simple is what you need. I've been using this heater for almost a month and I love it. Easy to use, easy to clean, works great - definitely recommend.
