Review on Mophorn 200W 18 Sound Loud Car and Truck Warning Alarm Police Siren Horn 18 Tones Fire Ambulance Emergency Electronic Siren Horn Kit PA MIC System for Ultimate Safety and Security by Michael Schafer

This is a fantastic product perfect for getting your friends and family nervous and terrified of the buzzer sound! I made the mistake of testing this in my gated 3 car garage and had to change my pants twice! Now I only wear brown pants. This horn/siren makes a variety of annoying and attention-grabbing sounds, including typical police/fire engine/ems sounds for different areas, including the ability to use a wireless microphone to disturb passers-by and small animals, the elderly and children . Pros: Easy to install. Cons: No manual, just a brochure with little English. There is no documentation for the MP3 function or the USB port on the main unit.
