Hotel door security alarm for the paranoid traveler

Just because you're paranoid doesn't mean they aren't after you

Hang this gadget on any metal doorknob in your hotel room and it will issue an ear-splittingly loud alarm of over 100 decibels whenever someone touches the doorknob on the outside.

Ideal for the security conscious, or to teach that chamber maid that the "Do Not Disturb" sign on your door means just that.
