5.0Amazing
Arrived fast and well packed. A small dent in one horn. It’s gonna happen. Still 5 stars. The sound is just as I hoped. Loud and full on train horn sound. We will use on our ocean boat in the fog. The ferries will love us in bad visibility. Maybe will let my granddaughter know we are in the bleachers at her soccer game as a surprise. Many ideas with the remote option too! Thank you
