There are several possible characters that your equipment can be while talking to you after giving it this perk. They all have different personalities, and will speak to you in a different way. The same gizmo will always have the same personality, no matter what piece of equipment you put it on. For instance, disassembling a piece of equipment with the Thalia personality, getting the gizmo back, and then using that same gizmo on a different piece of equipment will cause the new piece of equipment to also have the Thalia personality.
