The readable here 1-star reviews I would like to say: Even if the goods as "high security lock" is offered, I can not seriously due to the size and weight but such security. I think here we need to pretend nothing: If someone wants to open my suitcase unlawfully, it is this easy to succeed in spite of the locks.
But I see these locks is actually more than locks on, I desperately need for travel to the US if my suitcase is not to be broken by the inspectors. And the additional function "Search Check" (indicator turns red when the luggage was opened and inspected by officers) I think it's great.
