Works great but VERY loud

I mounted this inside the vehicle and wrapped it up with a towel because it was TOO loud to mount outside my vehicle.

Economical

This worked great for my application, not as a backup alarm but as an alarm for a cyclone bin full alarm. Works great and is loud enough to hear over the vacuum system.
