This video shows and explains how RaccAway works. (read text below)
“This is the RaccAway. It keeps raccoons and squirrels off your bird feeder pole. The way it works is that raccoons get on here, then slip off. Or if they put their weight on it… (vibration/noise) …that happens. Raccoons are afraid of two things: sudden movement and vibration. If bouncing doesn’t work… doesn’t scare them away… the vibration will. And your bird feeder is safe.”
