Mainstay has the best oil filled radiator heaters I have purchased of any brand, I always check the heat out put with a heat gun and Mainstay brand is the only brand I've found that actually puts out the amount of heat they are supposed to on the high setting.

I use this heater in a tack room that is not insulated well but it keeps the whole room warm and more importantly it keeps the water pipes from freezing. I like the slim design of it. I like that it's oil so I don't have to worry about God forbid fires, and it also has shut off Still you know if you drop it it shuts off I like the price and this stays on 24 seven pretty much from the fall to the spring.

Great heater to heat up a medium size room. I am sure it can work for bigger rooms as well. Turn up the thermostat only to the middle and at number 1. Heats the room well enough. Great for those days when you don't want to turn up the whole home heating on and save the gas. We usually have to turn ours off after few hours.
