I purchased these to keep my carry on closed and then re-purposed one to use as my gym lock. It served both functions well. Mind you these are a deterrent/impediment rather than serious security lock, they exist to make stealing from you less convenient and take more time. A good pair of pliers or a handheld bolt cutter would snip the wire within a minute. These locks do serve admirably in keeping my clothes secured in the gym, or keeping my carry on closed during a distracted moment in the airport.
