Review on 📢 Black Dual Air Horn - Kleinn Air Horns 102-1 by Tom Podolski

** Update after one year: small solenoid on failed. Replaced it with a standard 12 volt 1/2" NPT air valve solenoid for about $10. The audio signal certainly has more depth and boldness. Go ahead and upgrade the solenoid. Otherwise the audio signal was great. Really great sound! Loud and clean with lots of energy. Best value for loud beeps. Not "train whistle". The breeder's sound stutters, you pick it up. But seriously, the best value for money for a "real" horn. Really nice trumpet sound, low enough to draw attention when that dull blue hair is in a ultrasonic Mercedes. Have been in the truck for a few months now and doing great. More volume at 150psi than at 120psi.
