Very quick update. The armour itself is still a brilliant little thing. But it has one 'flaw' in general use. Its probably just me, but on many occasions when holding it while putting stuff in the car biot, I find I have fired it up inadvertantly. Somehow, when juggling stuff about to get things in or put of the car, I must be holding it in a way that makes it far too easy to hit that button bar. The shape falls into a certain way of holding it and then schhhhhhhh vapour. Not in any way a design flaw, it is user error. But I have tried burning a coil out by accident a number of times now so its worth a mention. Lock it and pocket it if you have your hands full.
