I bought a Travelsafe 12L Portable Safe for my Italy trip last year. We had planned several days from Naples south and eventually through Sicily between hotels where all our stuff would be in the car. Had read lots of online comments about potential car theft in those areas, so wanted to lock up our computer, ipad, etc.

It worked well and provided a little peace of mind, though not sure how big the threat really was? But I like the travelsafe and am now bringing it with me on all trips - locking up all my stuff and then putting the whole bag inside the hotel safe (and some safes have a metal loop you can thread the travelsafe wire through). I also changed out the travelsafe lock for something more robust.
