Used the lock on a trip and am pleased with how well it worked.  My TravelPro luggage has two zipper sections.  The flexible cable was the perfect length to secure both sets of zippers together so one lock secured two sections leaving no room to open the zippers even a little way.  Setting a new combination was simple. I did not find the cable mechanism difficult to use - push and slide left to right.  The numbers are a bit small and would definitely be difficult to read for some people.  Also, would like an indicator to show if the lock has been opened.  Overall, the lock did the job.
