Review on ☕ 25W Mug Warmer: Quick Heating Coffee Warmer for Office Desk with Temperature Control and Auto Off - Perfect for Cocoa, Tea, Water, Milk and More! by Tonya Brown

I've had several of these and this one has all the qualities I like plus it heats up more than most and quickly. It has 3 temperature settings, works with pressure sensitivity so it turns on and off when the cup is placed or removed. But you can also turn it off when the cup is in place! Nice feature as it works as a stand. Looks good, doesn't take up much desk space and has a digital display so you know what temperature is set. The controls are nice touchpads, so they're easy to use. Excellent all round.
