This desk fan is the perfect size and does a great job of cooling down a small room. We live in a two-story home and it feels like a sauna on the second story during Spring and Summer months. I am currently using this fan to redirect the air from the floor vent and it does a great job for such a small fan and saves energy so that I don't need to turn the thermostat down. It can be easily be mounted to the wall. It offers 3 speed settings and the fan head can pivot 90 degrees. We are so much more comfortable with this fan in our bedroom!
