I recently bought a portable space heater after hearing how powerful today’s space heaters are. And I have to say that I was not impressed with the one I bought. It was not that wonderful at all! Sure it did the job and heated the space I had it in, but I was not impressed by how it kept turning off no matter where I set the thermostat on it. I am not sure if maybe I bought a defective one and I need to return it to the store or what? I may have to go online and do some research on this particular space heater and see if this is an issue with all of them or just the one that I bought. If I find that this space heater is actually defective I will return the portable space heater to the store that I bought it from and get an exchange. I still have the receipt so it should not be a problem at all. But if there isn’t any defects and this portable space heater just does this as part of its regular workings, then I will still return it and just not buy this brand of portable space heater ever again! Like I said, I am not impressed by how this thermostat keeps going on and off on the portable space heater. There has got to be something wrong though. Because otherwise there would not be all the hype about portable space heaters today if they were all messed up like the one I bought is.
