This round silicone warming mat spreads even heat across its surface using metal heating wires underneath, keeping food warm for up to 12 hours. The touch screen offers 4 functional modes with adjustable temperature settings and real-time readings, so you can dial in warming, keep-hot, defrosting, or fermenting depending on what's on the table. A child lock keeps curious hands from bumping the settings, and if you don't set a timer it shuts off automatically after 4 hours of continuous use. The smooth, waterproof silicone surface wipes clean easily, and because it's flexible, the mat rolls up for compact storage instead of taking cabinet space like a rigid tray. At 4.85 lbs, it's a practical size to bring to birthdays, Christmas dinners, and catered parties. For best results, keep it off glass tables and use dishware with a flat bottom for quick, even heating.
