You get what you pay for.In general not a bad buy,but the door hinges do not support the door sufficiently.Consequently the door drops and jams on the bottom of the opening making it difficult to open.Anybody with poor grip would find opening extremely difficult.To install in an existing wall needs a fairly large hole made to insert safe into cavity and then to seal up strongly.The electronic control appears to work well and is simple to understand,but on this level and quality of security is it really necessary to have time,day and date displayed constantly?as this only wears flat the battery.
