In these hot and trying times, I ain't trying to fall out to heat stroke ya know. It really does move a lot of air fast too..
It is just as noisy as ¼ of a 4 arm/propeller drone. No speed control on this, it just runs off the raw battery voltage directly, so max speed.
I did have to flip the propeller backwards for the intended purpose, took a little modding ya know.
Since there's no blade guards, I set it up with a push button, in case anyone happens to drop it, it'll instantly shut off.
In my experience, it only takes about 30 seconds of use to cool you down to prevent heat stroke, and it lasts about 80 minutes or so of use before needing recharge.
