In reading these responses since the thread has been revived, it seems there's a lot of travelers (I'm guessing most are women) who talk about feeling more confident or secure with these products, and I think that's a key --- I don't feel unsafe or that I look like "an easy mark" when I travel, so I haven't felt the need to improve my security with respect to pickpockets or theft. I'm not saying people shouldn't feel that way; on the contrary, I think it's great that these products help with that. It's just a common theme I'm noticing, at least with the 2018 posts.
