Review on 🚨 Powerful 110dB MS-190 Industrial Alarm Sound Motor Buzzer Siren for AC 110V by Greg Usry

This is an ordinary fan in a metal case, nothing special. The picture is kind of deceptive in the sense that it looks like a real siren. Mine came with missing cover screws. When trying to test the device, a screw that was loose inside flew out of the fan like a bullet. I tried screwing it back on but found that the thin metal hole was larger than the size of the screw. I bought larger HD screws and had them repaired. Poor design but makes a noise similar to a drill. The noise isn't a discernible siren sound, and it doesn't have enough power to make a noise loud enough to travel from my detached garage to my house. 3 stars because it arrived on time and cheap.
