My favorite feature is the storage of favorites.
This one has to take himself to the most remote campground without network access to its "Lieblingsliederl".
But fun is the thing just only when the size of the display of the access device is also selected accordingly (it does matter from time to time to "size" to :-)).
My Conclusion:
My companion for hours together at the campfire (books tow was yesterday) until the phone / tablet battery separates me from my Chords.
