Ok to everyone who is scared from the first video I posted.
I decided to upload a recording of the noise it makes AFTER I turn the motor off. I repeat, this is about 30 seconds to 60 seconds after I have turned the motor off, not while it is running!

Now imagine that noise at your windowsill in your bedroom, late at night when you are asleep! I bet you, you all would s**t yourself!
