GET THE CONTROLLER TOO
This has done exactly what it's supposed to. Keeps my kombucha the perfect temperature, but make sure to get the "VIVOSUN Digital Seedling Heat Mat Thermostat Controller" so that you don't have to make sure its overheating. The mat itself will not shut off and supplies constant heat without the controller.
