A machine adapted by the military for one purpose: interrogation. The machine is not allowed to leave any marks on the user's body but has to create intense enough stimulation to force the subject to cooperate. Some tools include an adapted Transcutaneous Electrical Nerve Stimulation (TENS) unit to simulate tickling, vibrating pads, electric toothbrush attachments, sonic massage guns, mechanical scratchers with a small motor and spinning pads, and much more.
