I took the recommendation of Detective Kevin Coffee, an expert in travel security, and purchased the Triple Lockdown Luggage Lock. The way this lock works is that one end of the lock is secured to the handle and the other secures the zippers. That makes someone that uses a sharp object to open your zipper to cover their tracks since they cannot run the zipper back over the point of penetration. I also find this lock handy to secure my luggage in a hotel room. It also can be used to lock your luggage together when at the luggage carousel, while on a train, or together while checking in at a hotel. You can also secure you luggage or personal bag to a chair while eating.
I don't buy the argument that because something is locked it is an invitation that something of real value is in my luggage. I don't leave my house or car unlock so why would I leave my luggage unlocked either. If someone broke into my luggage they would not find anything of great value, unless you add up the cost of the clothes within, but what is in my luggage is mine and they want to peek inside they will have to take more risks then a piece of luggage that is unlocked.
When I grew up we never locked our doors to our house because no one ever broke into house back then but one day someone just walked in and help themselves to our things. My parents thought that was a fluke and refused to lock the house until about a month later the same thing happened. While the only thing stopping a would be thief was a pane of glass our house was never broke into again after locking the doors. Just last week a friend in a small town in New England and in her lifetime never locked their car in the driveway. They had their cars entered and things stolen, I would say broken into but since they didn't lock their car all the thieves did was open the door.
Is this lock going to guarantee that your possessions are not stolen the answer is no but I am not about to make it easy for someone either.
