This is a must have for the Boat, Car, Truck or even night stand. I fastened it to my truck tow hook and pulled it with my ATV to gauge what it would take to break the cable. My rear tires on the 500 Polaris. The box cable held so it would be impossible to snatch or break the cable. The box itself is sturdy and strong. The keys are a bit flimsy, but seems to be good enough. I keep my Wallet and pistol in one and the other has emergency funds along with passports and other documents so when the SHTF.
