I have one but I've not really experimented too much with them. I should!
Doesn't today's DotD have wiring so it's not technically remote although I guess it has an external stimulus being the mobile?
"The VibraExciter isn't wireless, it connects to the power pack by a discreet wire and a removable jack plug both of which can be hidden in a pocket or the waistband of your clothing!"
Have fun with it though. It's a great deal! =]
Ps. I am tempted as I do call my OH a LOT...
