Velocity 4 is a single room three temp setting space heater. The thermostat is a turn dial and does not have the degrees to show where a person wants to set it. It would be nice is it had them on the product like our old one did. It has a white noise that isn’t distracting. The casing remains cool to touch and does turn itself off if tipped sideways which are nice features. The area warmed up to a comfortable level quickly.
