For me, luggage locks have provided good service and some sort of peace of mind when traveling. Let's face it, if someone really wants to break into your valuables unless you have a heavy investment in seriously good locks, nothing will stop them. That said, I find these Samsonite combo locks to serve their purpose perfectly well. The combo is very easy to set or change, and having the side window allows you to easily see the numbers you are setting, as well as for opening. An added bonus is what Samsonite calls their "indicator feature." It is a little red color band that pops up to alert you that your luggage (ie the lock) has been opened. True, inspectors are supposed to leave their tag inside your luggage when they open and look but at least twice I have flown and I know someone went through my luggage and there was no such tag left. The indicator leaves no doubt that your lock was opened. Te indicator is also easy to reset. My locks are black. Other colors are available. I would definitely recommend these Samsonite TSA combo locks.
