So, I can get an item that will teleport me to someplace that's already accessable from all four nations (including Aht Urhgan!)? And because this ability to save me from walking 300 yalms is so awesome and powerful, I can only do this once a week?

Unless using it lets you exit to Jeuno, this isn't worth inventory -1. Can I voluntarily choose not to receive it? How long before a Porter Moogle will take it off my hands, ne'er to see the light of day again?

Another Purgonorgo teleport would mean more to me than this.
