As a hot sauce fanatic, I have tried a good number of hot sauces - Dave's Ultimate Insanity, Crazy Uncle Jester's, etc.  I put this near the top - it has a good mustardy vinegary flavor and a good amount of heat to it, without being too hot or flavorless.  I think they've found a good mix in this sauce, and I recommend it.  I cannot speak for the "phartpounding" action however ...
