If you are going to a dangerous area or need peace of mind, these neck pouches are great to keep thing safe.  I love international traveling and really love going to off the beaten path countries that terrify my mother.  I have purchased aleg pouch, a crotch pouch, and a neck pouch.  I regularly use the neck pouch.

Things to Realize: With all designs (neck, crotch, or leg) you need to be careful where you are accessing these hidden carriers.  If you are in Negro Mercado (Black Market) in La Paz, Bolivia, then don't whip it out in the middle of the street and then be surprised when a theif targets you.

The neck pack is durable, is concealable, and does exactly what it is supposed to.  One thing I do that I think has worked well for me is that I carry a fake wallet in my back pocket.  I keep small amount of money and old expired debit cards in there.  Thus, if I am robbed I will quickly offer that wallet and know that I lost a velcro wallet, some spending money, and expired cards.  In the neck pouch I keep the bulk of my cash and my cards.  When I know I'm going to spend some cash money I transfer money from my pouch to the fake wallet and only access my fake wallet in public.

With traveling in general, be wise about the things you do.  Don't whip out large amounts of cash in public, don't walk down the street with a map open in front of your face, travel in groups if in a dangerous area, know what transportation is the safest (are certain cabs licensed?), read up on the local scams, and be alert.  Follow these rules and you should be good to go.
