Query: Worthless garbage

I like the idea of this, but in practice it is completely worthless. The fan is so heavy that it causes the screw to rotate, making it impossible to make the fan stay in place where you want it to. Also, the neck is not as bendable as it looks. It simply goes back to a straight position after a few seconds. Save your money and save yourself some frustration... do not buy this.
