Decent suitcase locks - are there any?

If so got a link? The few we’ve had have been a gnat’s cock thicker than a human hair, & can be opened by sneezing

Thanks all. Yes I understand but my question remains. Occasionally one wants to lock eg samsung soft bags eg just if going in coach compartment or children going with school etc

So if anyone has half decent lock link would be appreciated - don’t need advice on new hard luggage, we have that already!
