This is the best metronome I have ever owned. I havde been playing by 'ear' and have decided to learn to play by sheet music. The voice count in is great (for me) .When turned off all saved programs are lost, which is the only down side I see. I really like this machine. If it were to break I would order another immediatly. I dont think it will break however,(knock on wood) I have a 15 year old boss DB66 which is still going
If you want the best, I believe this is it.
