Perhaps we should look at it from the point of NEEDS of the user.

It would seem that depending on one's needs, then one makes a purchase of a device hoping to fill that need. Is the marketing of the ITT done correctly/honestly? Is the impression given to the user who buys it correctly/honestly fulfilling its purpose described? Did the person buying have too much expectations of it or was that person fooled? Many questions...only the person buying it would know the REAL truth (pertaining to his/her own situation).
