This particular one is branded Genexxa and has megaphone functionality, as well as the ability to play a ton of pre-defined audio clips.

The music playback seems to work well but the megaphone portion is intermittent, the battery compartment shows signs of rust but still does power on.

I would recommend a clean to get this in full working order again, and while it has worked I'm offering it on an as-is basis due to condition.
