What I am Schloss is most disturbing that the bow during locking or complete is not held at both ends by bolts. In addition, you could relatively easily bend out one end, as it is not particularly deep protrudes into the lock body.
However, I must say that I use an ordinary suitcase made of thick fabric and a zipper. On one such case a more secure lock would have no meaning. Because it would be for someone who takes the trouble with the bending of the castle, hardly more difficult to destroy the zipper or the trunk material to get to the content. So it would make little sense to use a high-quality lock.
Of course you can use to travel a aluminum case with a more secure locking system than a zipper. Then another castle would also make sense.
But I think it is in any case so that any valuable equipment receives its place in hand luggage by my side.
In my view, a TSA lock you should anyway not use to another use than at the airport. Since TSA locks specifically distinguished by being able to be opened with keys from the airport staff, many keys are correspondingly outstanding. Accordingly profound is the probability that a non-authorized person may well find suitable key. In this respect, I would in any case never use a TSA lock for a different purpose, to cost as a potential case geezer some time.
