Christmas gift opened this morning by my son. He was delighted, he had asked the spy belt to Santa. Unfortunately, the amplifier, the Micro Agent Listener, passed away after 10 min. False contact, he walked randomly and in the same afternoon, nothing, not a single sound, we heard nothing. My son is very disappointed with his Christmas present and I regret this purchase. A bit expensive of the coup for accessories that do not last. Too bad that we can not put all the accessories on the belt. Only two accessories are scheduled to tie it. And it is the parents who must put them as too difficult for a child.
