Worked just fine.
I bought two of these locks to use on my recent trip to Australia.
Counting the flights to that country and within it, I traveled by air
8 times, and also by bus more times than I can count, along with
my luggage. The locks performed perfectly. The dials were
easy to read and to program with my own 3-number
combination. When I returned home, I discovered that one of
the locks had been opened and re-locked by TSA, thanks to the
handy red indicator on the lock. The indicator and combination
reset without difficulty. I highly recommend these luggage locks.
