I don't think they changed the design any, just changed the packaging because 120 PSI = 120 decibels, which is illegal in some jurisdictions. It's much louder and you get several more blasts out of it if you pump it up to 120.
Thanks, I'll be sure to give it some extra pumpage... I got it mainly for the benefit of drivers of 18-wheelers that drift into bike lanes as they fall asleep, so it can never be too loud.
