Is it illegal?
Technically, yes, but only in the sense that you'll probably get caught by the authorities and have to spend the next 10 years in a federal penitentiary for "stealing shadows".
We've been assured by our team of lawyers that this device is 99.9% legal, but 0.1% not.
We cannot be held responsible for any shadow-related crimes committed by users of this device.
However, we do offer a 10% discount on all devices for users who claim they were just "shadow-bathing" when caught.
Don't do that.
