My dog hates them and I never really seen the point in them once I grew up, I don't think the displays added anything to my childhood.
Don't really understand the need for the ones that are so loud, not for private sale anyway. Bet there's plenty of folk with PTSD and other sensitivities that this really isn't helping.
Just limit loud ones to public displays and have the public displays at the same timeframe, how difficult is that really? 4 hours of loud bangs on housing estates is a bit difficult to avoid.
