Review on Chefman Compact Glasstop Warming Tray by Chris Horton

The product worked perfectly during the 2020 Christmas dinner, but one of the three heaters did not stay on during the 2021 Easter dinner. It looks like a short has occurred if the heater turns on and off when plugged into an outlet. The other two heaters were plugged into the same outlet and kept warm throughout Easter dinner. Waste of money as I can no longer return the product.
