Stable and has some decent features, but lacks some very basic functionality that any decent music player should have. Unfortunately that somewhat cripples the very good (and expensive) hardware it is the only controller for. Devs need to look at poweramp full version to see what a real music manager/player is and is capable of. (Not to mention the level of configurability that's so lacking in bluos). I only continue to use this software as I love my powernode, but I wish it was complete.
