I had a small radiant heater I bought at Harbor Freight, it didn't even have a name on it. It worked really well, I used it in my 9x12 kitchen almost 10 years, it finally wore out. I bought the Wave3 hoping it would be as good. It did so little I returned it thinking it was defective, a replacement came the next day, and it was damaged, the thermocouple was way out of place. I almost thought Amazon shipped me one somebody else sent back that they just had hanging around. I readjusted the thermocouple and it worked, but was completely inadequate. One of their larger ones may be fine, but that Wave3 very wimpy. Maybe extremely wimpy is a better description.
