I like that it's easy enough so anyone can use without much training or help needed at all! It also gives you an option when using your phone if someone else takes over while doing something important (like talking). You cannot easily change how many hours are used before charging etc., but there may be ways around this depending upon what features they add next time out? Not sure yet as haven't tried any other apps/services recently - just right now trying everything under sun until we find one which works best within our needs though still not found anything great thus far either way!!
