The spell is limited to bringing small objects toward the user and cannot be used for object that cannot be grasp using one hand . Multiple objects also can be snatched using Aports as long as all of them can fit in the user's hand. It also shown that magic nullification can cancel out the Aports. Yet when inside magic interference barrier, Aports still can be used.
For using Aports, the users usually need to see the object However if the object is not visible, a similar object can also be used for visualizing the object in the user's mind before using Aports. With Aports, the object is not moving toward the user but it appeared as the object is being teleported to the user's hand.
As Elze pointed out and Touya's self reflection, the Aports user could easily pickpocket anyone's belongings and no one would be able to detect it. The spell has proven useful in battle as Leen commented about how Touya was able to steal the Immortal Gem from Yamamoto Kansuke.
