If it helps as a deterrence then good, desperate times, mate I'm not a genius in this field.... I'll put an alarm, it may work it may not, if it doesn't I'll get your mate in the advert to make my van bomb proof! If that doesn't work, I'll strap an uzi 9mm to the sliding door switch, mate if that doesn't work, I'll give up my career and post my cv to tescos as a bean stacker! Cut me some flipping slack Jack. I've just had my van robbed. I haven't advertised to thieves come get my tools, I haven't left my doors open, people don't see what goes in my van and what doesn't like some of you have suggested, taking tools into your house which I feel poses more of a risk..... potential thieves seeing good brands whizzing into your house.
