Stay away from BIGHORN
Having owned one, I cannot recommend BIGORN safes. The safe appeared reasonably well made and fairly sturdy upon delivery. Unfortunately, the locking mechanism failed two weeks before the 1-year warranty expired, and I would say that during my 11.5 months of use, I probably openned the safe less than 25 times.
When I contacted BIGHORN to describe the situation - basically unable to open the safe due to a stripped out lock - the technical support person knew exactly what I was talking about, and over-nighted a repair kit to me, then contacted a local locksmith to open the safe and repair the lock. It took the locksmith almost five hours to open the safe, not because the safe was some kind of impenetrable marvel, but simply because the cheaply made lock and internal mechanism was so out of whack. Once opened, the locksmith was able to show me the cheap pressed steel used for the lock mechanism, and just how soft and easily stripped it is. After I saw this, I immediately contacted CostCo for a complete refund, and to the credit of CostCo, was taken care of literally within 5 minutes.
Do yourself a favor. Save up a little longer and buy an American Security safe. Much more expensive, and worth every penny.
