Amazon.com.au:Customer reviews: TSA Approved Luggage Combination Locks, TERSELY (4 Pack) 4 Digit Combination Padlock with Alloy Body TSA Lock for Travel Bag, Suit Case, Lockers, Gym, Bike Locks or Other
TSA approved lock is an important feature that I found very useful during the international travel. These locks have big enough steel shackle that is easily used with all of my suitcases and bags. Now I feel hassle free being Key-less. Its four digits locking mechanism provides me 10000 combinations to set. I am also using one lock for my mailbox and now I can open mailbox without any need of key.
