lets work on it!
After reading all the posts about this topic I decided to check out their websight… What I joke Ill continue to stick with HornBlasters 
I am frustrated!!! In short, I ordered a horn kit (el diablo) a couple months ago. I called them back and asked for a wiring diagram…they directed me to their web site…very lack luster diagram. They told me they were going to send me a detailed one…still have not recieved one.
Expecting one port in the pressure gauage there where two…trainhorns.net explained to me on the phone the two ports where an input and an output. Not true…two inputs for two tanks…silly me.
I said screw it…had it wired professionally only to have the dude tell me the compressor was defective. He also suggested a better quality compressor.
I called trainhorns.net only wanting to exchange and then give them more money for a better qulity compressor…silly me!! They explained under there terms and conditions after 14 days they will not take it back. They advertise 1 year warranty, money back garuntee and tech support…bottomline: they do not back their product after 14 days…and do not really have a “tech” support department.
Hornblasters always gets great reports on their customer support. Why go anywhere else?
