Spy Review

This innocuous looking box when attached to your phone is an innovative gizmo which can monitor the other party’s conversations. Say you are talking to somebody on the phone, but want to know what he is discussing with other people in the room. If the gadget is attached to your phone, you put the person on hold. This hold is not real, but the person thinks it is.

The hold invader thus acts like a room bug and you can hear whatever conversation or sounds are emanating from that end of the line. In order to get the best out of this gadget, you should start the conversation and while it is at an important juncture, interrupt and put the person on hold, saying you have to attend to an incoming call (it has a built-in incoming call simulator) and put him on hold.

While that person thinks the phone is on hold – and there is a dead sound on the phone – he may say something incriminating, or something which may be of use to you in some way. He won’t be able to hear anything you say at this point because your phone’s microphone will be cut off. When you get back to him, you will be in possession of important information and this can be of use to you in business negotiations or even on a personal level.

Originally designed for a federal investigative agency in the US, the hold invader is intended and sold only for legal and lawful use.
