Magazine Reviews 

  • Practical Caravan Guide to security: "A clear winner very sturdy indeed, I would be happy owning one of these." 
  • Practical Caravan Magazine: "The attack needed to breach this lock could wake the dead. Its essentially a super tough steel box, all the locks are enclosed and there are no obvious access points." 
  • Auto Express Best Buy: "There can only be one winner and our choice is Bulldog." 
  • Caravan Club Magazine: "It is one of the best out there"
