I had ordered this heater a short time ago, and i was really surprised at how fast it came! I have to admit, i was not expecting it to work as well as it did! I was extremely impressed ! For such a small machine to put out that much heat 60- 90 degrees is simply amazing. The Vornado Velocity 4 Whole Room Space Heater does everything it says it will do. It has a handle for moving,a cool touch case, plugs into a standard wall outlet, has safety features,such as if it tips over or the airflow becomes blocked it will automatically shut off. Plus the Vornado Whole Room Space Heater circulates heat faster and further throughout the room. When it becomes dusty just wipe down and brush off, simple as that.
