I've been using the Pacsafe Travelsafe 100 for the past 5+ years whenever I travel overseas.  If you only stay at hotels with in-room safes, you should know that hotel staffs have a key that can open your safe without your knowledge.  The hotel staff will remove a few bills or cards so as not to be immediately noticed by you.  In these situations, I use a Pacsafe Travelsafe to secure my belongings and place it inside the in-room safe.  If the Pacsafe Travelsafe is missing from the in-room safe, then you know it was a hotel employee who stole it.  When not traveling overseas, I also use it in my car to secure my keys, wallet or other valuables when I go camping, hiking, or kayaking. So far, so good.  My car has been prowled, but my Travelsafe and its contents were not stolen.
