This is a good cable to help avoid casual theft.  It's lightweight and someone would have to use wire cutters to get through the cable or the lock.  This is best described as an insurance policy to keep honest people honest, and to give a thief pause.  Inside of airport security, I only really use it to secure our carryon bags with cameras, ipods, etc.  and my wife's purse.  Those are small and concealable.  We don't feel the need to lock down the rollaboard.  I regurlarly use it on everyhting when in bus or train terminals.  When travelling for business, I do use it to lock down my laptop bag pretty much everywhere.  For what it is and how I use it - 5 stars. Hope this is helpful.  R
