Our take

Why it caught our eye

Most mug warmers look like coasters with a plug. This one looks like a rug that has shrunk to fit your desk. The joke is clear from across the room, and it still does a proper job. It's a good pick for the coffee drinker whose drink always goes cold at the second sip.
