Untrustworthy.
I am not a lock expert so I called Van Delft…read more I asked for my entire door lock to be fixed, but the locksmith only changed the door handles. After he left I saw that lock was still useless (the door could be opened easily by pushing it) and that the new door handles were even still a bit loose (not tight against the door). The locksmith should have better examined and told me that I needed to change not just the door handles but also the lock.
Now, they will not accept to fix this poor job without making me as a client pay twice for the work like an idiot.
