You've got to admire the ingenuity of folks like this.
Personally, I'm usually happy to just do the simplest, which might be to just back out with the beeper making unpleasant noises! But, that someone would even think to come up with what appears to me to be a very simple concept excites me!
More power to these creative people! Even should they only sell a handful of their gadgets, methinks that's successful! :-)
