Well- it seems to be sturdy, and fits my new passport (the one with the chip).  I haven't actually traveled with it yet, but I don't foresee any problems.  It covers up the big USA seal on the front, which was one of my goals with this cover.  I'll be traveling places where that isn't necessarily something to advertise.

Anyway- looks good, has a nice texture, and doesn't feel cheap.  And it's unusual looking, not like the typical black leatherette!
