Forge TSA Approved Luggage Locks for Air Travel, Gym Lockers, School Lockers, Pelican Cases, Easy Read Dials, Durable Alloy Body, Black 6 Pack.

Great extra layer of security for your luggage whenever its out of your sight and control. 4 pack is a great value and we travel with them all the time.

These were fairly easy to set up with the FOUR digit combination I chose, so they are a bit more secure from the thief of opportunity. Obviously anyone with even a short handle set of bolt cutters can easily cut these. That isn't the point though. This isn't meant to stop a determined & prepared thief, it's to keep casual passersby honest, and stop or at least slow down the casual thief enough that they move on to an easier target.. The only negative is that the silicone caps provided for color are next to useless. The rolled up or off many times, until I threw them away. I can't say if the TSA alert buttons work, as the backpack I put these on was never searched beyond MY emptying items out at the checkpoints.

Went on vacation, and used these locks to secure suitcases. The locks worked great, despite passing through 6 airports. Also kept things secure while luggage was transferred from hotel to hotel, no issues. The only difficulty I had is at one point one of the locks would not open with the assigned combination. I thought I would have to retry all combinations, but I guessed that I had inadvertently moved the shackle so as to change the combination. I tried combinations that differed from the assigned one by one digit, and found the one that opened it, then I reset it back to the original combination. Locks will not open if digits are not exactly lined up, but I can't say that is a problem. I don't think the TSA opened the luggage. I am very satisfied with this purchase.

The locks are easy to use, simple instruction, great quality locks!

Used to secure firearm, and luggage when fly to Alaska. Convenient that you can set you own code. Not big and bulky like others I tried. Seems good quality.
