Review on YHAAVALE 9200E Amplifier Emergency Police Siren & Ultra Slim Metal Octagon Compact Flat Speaker, DC12V 100W Multi-Tones Wired Control with Mic Loudspeaker Electronic PA System for Police Vehicles by Jodi Tisdale

The device was easy to install. It makes a siren sound as advertised. But I expect everything to work as expected, and this device doesn't. Worked fine initially, but now, just a few weeks later and with very little use, it doesn't turn off with the power button as intended. Leaving it on drains the battery. I would return this product but it is already installed. As indicated in the instructions, if you have any problems, contact the company via email. I did so and asked to replace the controller but after a long wait I received no response. I decided to post this review. So to sum it up, cheaply made and no customer service I would advise you to ditch this device and buy it from another company.
