For as small as it is... HOLY CRAP
Ok this little horn packs a wallop of a bark. This horn may be only a touch over a foot long and 3/4 of a foot wide but do not underestimate it. I about crapped my pants when I first touched it off. Crazy loud and scared the crap out of me. I first bought it when I still owned my 2008 Honda Fit. I used it predominantly as, what i referred to as my "tailgater horn". Whenever someone would try to inhale my exhaust, I would let it rip for about a second. That would be enough to startle them and they would back off. If you want a horn that is reminiscent of the typical semi horn... only FAR LOUDER... this is the one for you! awesome horn, I highly recommend it!
