HEATED TRAY small, 1970s. Keeps food and beverages HOT. No on/off switch. Just plug/unplug. Ill keep my teapot on it. 2$. So awesome.

This is about as long as a computer keyboard and twice as wide. My grandmother had a much larger one she would set out on a buffet to keep the 
Hors d'oeuvres warm.  Like hers, this one to the right -->  It gets HOT. it says "hot electric tray" not "warm electric tray". its the truth. You could'nt cook on it but it will keep your food HOT not luke warm. I wonder if regulations have changed because it seems like food warmers don't do a good job anymore. I bought an electric cup warmer once. To replace an OLD one. And the new one kept the tea from being "not cold". Not warm, not hot and "not cold". It was wasn't effective. So i returned it and bought a different brand. Same problem. "luke warm tea". not worm but Luke. use the force. to warm up. the tea. so ya. This electric tray will keep my teapot HOT. I have a metal teapot that can't go in the microwave.
