Query: Not worth the money

This was purchased as a gift for my mom who has a hard time dealing with a regular remote after her strokes. Spent a good hour or so 'training' the thing to our voices. Don't know why - it would just change channels in the middle of a show and when you tried to tell it the station you wanted, it wouldn't change. So for all that training - it didn't seem to hear a difference in voices and any sound apparently will trigger it to take an action.
