Mobile Phone Signal Stopper (MPS-2) is the best simple time-tested solution to restore the peaceful and tranquil environment you want and in many instances, must maintain. Just the single ringing of a mobile phone or pager can be devastating to the ambiance of a fine restaurant, the professional tone of an important staff meeting, the excitement of a casino, the respectful dignity of a place of worship or the enjoyment at the theater for both the performers and the audience. With a rapidlygrowing number of mobile phone users worldwide, what was once a quiet and peaceful environment has become filled with rings, beeps and musical tunes amidst loud mobile phone conversations. There is also the dangerous risk that a mobile phone can be used as a remote detonating device to set off explosives.
