Yes, the Vibro Agitator is a photo product. I believe it's designed for the photog to place the developing tank on top, then switch it on -- the Agitator vibrates and so transmits the vibrations to the tank, thereby performing the "agitation" automatically, and with repeatability. I don't know if this LPL product provides constant agitation or intermittent agitation. Obviously one would have to a lot of testing to determine correct development times when using this device.
