Best heater under 20 bucks

Purchased this heater from Lowes for $15.88 on sale. Features include a small footprint, real thermostat and two distinct heat settings. While the range of automatic setting is in 5 degree increments, it does at good job of maintaining the set temperature. What amazes me is the heat output. The swirl grill resembles the Vornado and dispenses heat uniformly throughout the room. It is not the quietest heater on the market, but, you get what you pay for. Last but not least, it does come with a three year warranty.
