I bought this for my 9 year old daughter. She was very excited based on the TV ads. The lie detector kit works like the real thing as it tests for increased sweating through the fingertips. However, most children are not really going to sweat when lying for a game!! So, everyone seems to always be telling the truth. Not really what she was hoping for. It comes with a little pamphlet on other clues for lying like eye contact, body language etc but unless you are going to ask your brother if he stole your favourite teddy bear, not sure it has much value.
