Doesn't give you a "full " range of adjustment

Only the top third of the adjustment is usable. Below this value, the fan only makes noise, but spins so slowly that it produces little to no airflow. So the setting is a bit more sensitive than we would like. I am using this with a Vivosun 4" 195 fpm fan. Your results with others may vary.
