What is the maximum operating time of foot warmers? Can they ope

There is no limit to the maximum operating time of the foot warmers. Our employees have been using our foot warmers during working hours for the last three years, for more than eight hours. The foot warmer works continuously in the turbo mode or as long as you rest your feet on the device. Settings can be changed during operation using the remote or the control panel located on the device itself. The device enters suspend mode when you lift your feet and shuts down after a predetermined amount of time, and resumes operation when you rest your feet again on the device. By doing so, the heater both conserves power and eliminates the risk of accidentally leaving the device on.
