To the naked eye this looks nothing more than a casual multi-block and can also be handled without arousing suspicion but it is in fact a solid state GSM transmitter offering unsurpassed listening quality.

This means you can actually listen into a large room and even further through to another room. This is great for extremely long term surveillance as the strip is powered from the mains supply so no batteries are needed.
