Save your money, bars and shutters will only keep honest people out, invest in a
good quality security system. We have bars on all windows and doors but it didn't stop them,
they got through them without any damage, they also managed to open a door without any damage, amazing!!!
But as soon as they opened the door the alarm system triggered and they fled without even setting foot in the place, now they know the alarm is genuine, not a dummy box, they will go somewhere that isn't alarmed.
