I ordered this TSA lock for over two years ago for me and my students for a student exchange program in the USA and have again given a large order recently. I am still very pleased with this castle. How have already written other, it could be open by gross violence by others than the TSA authority, but that's in the simple case locks that were previously in cases going even easier. And that the TSA authority may open the lock, I realized after returning a few days ago.
