Review on Personal Adjustable Thermostat Protection Certified Heating, Cooling & Air Quality by Maurice Branch

I've only been using this under my desk since yesterday, but it's been great. I rated the warm and warm three stars because it doesn't have to be a real high power heater. The 1200w heater I used was stuffy. The device is small and has only one switch. In other words, there is no adjustable thermostat. But since 600W is just right for my cold store, I still want to run it for hours. If there's too much direct heat, you can just adjust it so the fan isn't blowing directly at you. If it's still too hot, you can turn it off. The fan is not very loud at all. It may be obvious to most people that even a small 600w heater will NOT run on battery power. However, I know some people have been misled by photos that don't show the cord and thought it was battery powered. This heater uses a cord and requires a standard North American 120V AC outlet. But since it's only 600 watts, it shouldn't overload the house's circuit breaker and wiring. As long as this heater lasts, I'm perfectly satisfied.
