The Shanling user face is quite intuitive and easy to use.
Utilizing a multi functional wheel for scrolling and entering, and a smaller button to go back.
Admittedly with a bevy of Android touch screen devices around me I would often pick up the Shanling M3s and tap tap at the screen for while before realizing what I was doing. Cue sad trombones and face palms.
As you can see the screen has good resolution and the menu can be clearly seen.
