My husband and I both used one on our trip to Italy, and I'm so glad we did, because they kept our passports and credit cards and money safe, whereas someone else in our group got their wallet stolen coming out of a gift shop.  Anything that is important to you should stay on your person, not in a purse or backpack!  We wore it under our clothes, so it was not visible to the public.  I like the two zipper compartments, because one can hold your credit cards and passport, the other can hold your cash.  That way you are usually accessing your cash, and less often accessing your passport and credit cards. I also like the RFID Blocking feature, feeling that everything was very safe from pickpockets or ID thieves.
