Rexmon Coffee Mug Warmer, Electric Coffee Warmer for Desk with Auto Shut Off, Smart Cup Warmer for Warming & Heating Coffee, Beverage, Milk, Tea and Hot Chocolate (Multicolor - Mug Included)

It's a cute looking product. It works quite well.The only drawback is it takes time to heat up. So if you want to use it for keeping your tea or coffee warm for more time then make sure you plug in the product few minutes before you use it.

It could not even heat a small cup of tea... Not worth buying
