Reviews for Safe T-sensor"This is a great product, extremely easy to install. I’ve had a house fire in the past, so am extra cautious around the kitchen. You simply plug the microwave into the plug so it can auto turn off if needed (so it’s safe when you’re not home), and the alarm is magnetized to be placed on the microwave. I tried the test button and it’s very loud. I think this could be used for more than just microwaves as well."
Excellent recent review from November 2020
