Does anyone know if the mini voiceboxes being sold (by Jupiter and others) are the same dimensions as the full blown voiceboxes?
Like - the actual lighted area... is it the same size on the mini voiceboxes as what they use for the more expensive ones?

No one knows? I've sent numerous emails to Jupiter electronics... and have never received an answer to my question.
So - any suggestions WHERE to get a voicebox? Best?

I don't think so. But I could be wrong.
