Kleinn Air Horns RAMHD-734 Black RAM HD Onboard Air System (with model 230 train horn)

First of all, these horns are GREAT - when they work.Installation wasn't too bad, but not all of the threads are the same - and I have no idea why. But after a few trips to the local hardware store I finally got them installed.From the beginning, not all of the solenoids would open when the tank was at 150psi. I cleaned each solenoid, made sure they were installed correctly for the air flow, and even installed thicker gauge wire - and they still won't always open.Then a few months down the road, the pressure sensor stopped working. So my tank would dump the pressure once it got too high because the sensor didn't turn off the compressor.Then 1.5 years after installation the compressor died. My horns on my previous truck were a cheap set, yet that compressor lasted many years - this one, not so much.I'm pretty disappointed in this setup - I figured they would last longer than what they did. Especially for what I paid.

The box came in kinda in bad shape, when I started going through the fittings and parts I noticed that it was missing some fittings for the air tank and the air filler hose is not a long one, it's a set of two small hoses. One of the threaded fittings was damaged when unscrewing off. Overall after paying over $1000 I expected not to have missing parts and better quality fittings. Not worth the money for the parts and attention to ensure that all the right parts are included.

Oh my god.... I have scared the crap out of so many people
