* It is easy to lock it so that the combination indicator/arrow points downwards - which means you cannot see the combination to set to so that you can unlock it. If you land up in this situation, the only way is to lift the laptop along with the lock and set the combination to unlock the lock - while you are lifting the laptop.
I know - my second observation is hard to understand unless you actually experience it.
Dump this Kensington lock. Instead, go with the Targus DEFCON CL Cable Combination Lock.
