Annoy-a-tron 2.0
Now that they've mostly recovered from the twisted mind maze that was the original Annoy-a-tron, send them on a new journey of "self discovery" with version 2.0 Now featuring 6 sound choices plus volume control, it's at least twice as fun (and annoying) as the original. For effective deployment, we humbly suggest the following sound and volume combinations, but you can conduct your own field research for more insight. 15kHz (Teen Buzz tone** - young folks can hear it, older folks cannot!) (full volume) Cricket chirping (medium/low volume) IM Doorbell (low volume) Grating Electronic noise (full volume) Typical Electronic Beep (medium volume)
