I bought this item for travel in India and Asia where I knew I would travel on trains.  It was perfect for securing my suitcase/backpack in hotels as well.  The cable is long enough to secure two suitcases and small backpacks on a train or hotel - although I did buy two (one each for my husband and myself) so I didn't have to smash everything together.  I don't think it provides security for really savvy thieves, but for quick grab and go thieves it is perfect.  I travel all over the world frequently and take it with me on every trip.
The combination lock is small and has only 3 digits, but that also makes it easy to use.
