At first glance, the self-contained Burglar Blaster security system seems neat. It's quick to set up, covers up to about 190sqm and will stop intruders with a shower of pepper spray. Nothing could go wrong with that, right?
Except what if you stumble into your home one evening and struggle to disable the system using its key switch? Will you remember where the concealed manually activated on/off switch is before your 40-second window is up? If you think you would be fine and survive tipsy nights without pepper-spray blasts, then feel free to pick up one of these security systems for $US600. [Burglar Blaster via Uncrate]
