Was planning on having the security Glass fitted by Pentagon in Reading, Berks. From what I can gather they seem to be one of the market leaders. Its not just a case of someone breaking in im concerned about but also the possibility of a side on collision. I'd rather the window stayed in one piece, instead of shattering and sending hundreds of pieces of glass hurtling towards myself. (And anyone else in the car for that matter). I do see what u mean though about someone breaking in. If they want to do something they will.
