I really really need one of these. Well, maybe not need, more want. A cellphone jammer with a 30 foot range. Can you hear me now? NO! Costs about $400 with all the accessories, so it might be hard to justify. I’d happily settle for a bluetooth jammer that kills those retarded borg looking earpieces. Guess I’m just nostalgic for the days when only crazy people carried on conversations with themselves.
