I got these for myself and my daughter to use on our black suitcases. We are traveling by air and I have heard horror stories of rummaged luggage left unlocked, but I also know that if TSA can't get in to your luggage when they want to, they will break apart whatever they have to.
This set of locks is able to be opened by TSA on demand without destroying the lock, zipper or luggage.
I chose the purple locks so when our bags come off the carousel, it will be easier to spot ours from other bags.
They open easily and feel strong and sturdy. I was able to feed them through the zipper pulls easily as well.
I would buy these again.
