The lightweight TravelSafe 100 Portable Safe folds small and is easy to take with you whenever you need to lock and leave your valuables. Featuring the eXomesh Ultimate complete lock and leave system, the TravelSafe 100 is especially handy for securing your valuables in your suitcase, hotel room or even at home.
PROS: I am a big subscriber to the philosophy that you can enjoy yourself much more, without being idealistic and myopic, when you know that you have taken one further step of deterrence to protect your things while traveling. This device is the perfect size for all my high cost valuables, save a laptop, that don't necessarily walk with me when I'm in a hostel or even nice hotel. I know that I can secure it to the door hinge of my room and when I come back it is far more likely to be there than otherwise. Nothing is theft-proof, but this will make you no more than person 99 on that day's list of the thief's top 100 possible victims.
CONS: Little pricey and little hefty/stiff. But those are unfortunately necessary evils in my opinion for this application.
