Yea, me too Gerry...but these are inexpensive, easy to use and carry, and kind of scary when they activate.
I'm sort of running on the assumption that anyone who might want to sneak into my room in the middle of the night probably wants to do it without waking me or anyone else up...at about 120 decibels these things are enough to wake the dead (or heavily rum impaired)
Still don't like the fact that I even have to think about packing a security device in the first place...we should all be able to relax and enjoy our time on vacation, right?
