Yeah thatās pretty much it, I mean, thereās a lotta jokers out there selling āTrain horn kitsā with super inflated outrageous decibel claims, no phone numbers or contact information on their website, no support, no feedback, just blowing out cheap-o air horn kits out of really inexpensive imported parts and really screwing over a lot of people. The facts are this, Weāve been around for a long time, if not the longest (check our domain registration by doing a whois search on our domain hornblasters.com by going to netsol.com, then checkout older versions of our website on the internet wayback machine at archive.org as you can see, weāve come a long way) The competition talks dirty, we let our horns, and our customers (and return) customers do the talking for us.
Hornblasters kits are the bestā¦ Way better then any of those horns you see at truck stopsā¦ And matt is a great guy to deal withā¦ Plus I believe hornblasters kits come with a life time guarantee on their hornsā¦
