Review on Convenient Coffee Mug Warmer: Auto Shut Off, Ideal for Desk Office and Home Use by David Reyes

The smooth surface means a person or animal can easily knock over a mug. I have a cat. Shuts down at an average liquid flow of 12 ounces. the cup is half full (or half empty). The whole point of the warmer is to keep the drink warm until the mug is empty or almost empty. It's difficult to see the indicator light at an angle when you're sitting at a table and the warmer is sitting on the same table, which I think is the most common use case. Wanted to like it as it has a simple clean design and was reasonably priced but I'm sending it back.
