Review on 🚓 CARMOCAR 100W Car Siren Horn - 7 Tone Sound, Police Mic PA Speaker System, Emergency Microphone Amplifier. 12V Electric Horn for Emergency Vehicle by Nick Mcvey

Much better than expected. Because it's $20 I thought it was a cheap piece of plastic that would break. I was wrong, much louder and better than expected. If you want to install it properly (like mine) you will need to buy some extra screws. The only complaint is the weight of the PDA (it's pretty light) and the assembly of the rest for the PDA (probably going to break soon).
