When a child wearing our prosthesis comes to a kindergarten, other children usually show interest towards the shiny gadget. It is hard to resist such a noticeable device, especially with, say, someone like Spider-Man pictured on it. The children get interested in how the prosthesis works and what can one do with it. If the prosthesis breaks in the process or its paint gets stripped, we take the device in for the warranty repair. Such cases are useful for us, as they help to improve our products.
