DeFIBulator, the voice tension detector can help you see if anyone is lying to you. A real interesting device considering that it is a handheld and making the very famous lie detector reach our homes. Sounds like a real kid party booster or even for family fun. However I would not suggest anyone to purchase this and test very important issues because lie detectors are far from being perfect.
You can buy this device via GadgetUnivers for $49.99.

so what do you do exactly…put it in their hand and say “now please say that again…I just need to know if you are lying to me or not”
