Great safe for the price. Lets face it no safe is break in proof. Criminals will always find a way. Most thefts from an auto are smash and grab of items left in plain view. Radar detectors, GPS and other items are generally taken by breaking a window. This little safe will definetly stop a casual theif. If they want more then they will steal the whole car and have all the time in the world to crack a safe.This was easy to install. Loop the cable around a seat bracket and pass the large loop through the smaller one and then put the large loop around the locking mechanism inside the box and pass the cable out through the slot. Less than one minute to install. I am buying a second for my other vehicle.
