A friend has bought the castle from your local supplier. Out of curiosity I tried to feel for the numbers - and lo and behold, at the first attempt, I had the lock open within one minute. And as an absolute layman! So I can really only advise against this combination lock!
It is beyond me how a reputable security company can offer all seriousness such an insecure technology.
(... The friend has the castle of course exchanged immediately ...)
