It may seem simple, but the flexible cable design makes it easier to put on and take off of a suitcase. For suitcases with fabric covering the zipper area, this especially holds true as the lock hangs down just enough to adjust the numbers and open it. It's also small enough to sort of tuck away under a zipper covering, at least on my bag.

The combination was very easy to set and since they are TSA accepted, you don't have to worry about the lock being cut off if they need to access the bag for some reason. I've traveled many places with it and it's nice to have some additional peace of mind. Well worth the investment!
