Used this two years ago when we stayed at a place with no safe. Locked valuables in it and locked the cable to water pipes. Not foolproof but the average thief would have a difficult time in opening. It is nearly as secure as described in the ad. Felt pretty secure when out of the room. Would recommend if no safe available or for beach or car.
Did not use it outside the apartment, but this year we will have a jeep for our 2 week stay. Think we will use to secure valuables to the jeep.
