Even though we never put any valuables in them, each time we flew one of our cases would be opened and the TSA lock never replaced. We started using coloured cable ties a few years ago and since then have never had our cases opened. I also remember seeing a video clip showing how a thief can insert a pencil into the zip of a case, force the zip apart and remove a small item. The locks can then be used to slide along the zip and back to close the teeth. The owner is then unaware that their case has been tampered with until they reach home.
