I will say this--in my short comparison I did notice one critical difference between this fan and the smaller one. While the smaller fan was able to deliver more concentrated airflow at a higher velocity (even on its lowest setting), it is a smaller fan.
The endless breeze fan is much larger so while it is not moving the air as fast, it is moving a larger volume of air. Not sure how that affects the fan's ability to keep you cool.
My primary intent for the fan is to use it after 9pm when I need to shut off my generator and have it sitting next to my bed blowing directly on me while I sleep.
