Is this Mordor

Or is there a dalek in my bed?
Hubby has one of the Actipatch free samples.
He wears it on his shoulder.
It has a little red light on it.
In the middle of the night, it shines out.
When he's laying beside me it looks like the eye on top of the mountain in Mordor.
When he gets up and shuffles to the toilet it looks like a dalek wandering around the bedroom.
