However, for good safes, there's a rating on how long it takes.[1] Ratings start at TL-15, for 15 minute resistance against hand tools. They go up to TXTL-60: torch, explosive and tool resisting for 60 minutes. Safes with these ratings will have a metal plate indicating UL testing and approval.

If there are any rated safes on Amazon, I can't find them. A real TL-30 1 cubic foot safe sells for about $2000 and weighs about 500 pounds. Amazon sells something that looks similar for about $100 and weighs about 15 pounds.

There's a separate set of ratings for fire protection, from the NFPA. Fire safes are much simpler. They have more insulating materials and less steel.
