Bought as replacement for a lock that had worked for 30 years; hopefully this will work as long. Quality of construction great; details held on the Safe site really helpful in identifying the correct replacement (the old lock was unbranded but is obviously exactly the same model). Extra keys cut by Safe and deleivery all as expected - fitting into the existing cut out was no problem at all. The level of dimensional detail held on the Safe site really helped and the supplied product met all expectations. Would definitely buy from Safe again in future - the prices were right too.
