Out of the box you can tell this is a premium tuner: it is well made, the way it feels, what it looks like, everything shows quality. It is clear to see, although I haven't used it on stage yet, but I would be surprised if I was to have any difficulties.
I find the buttons on the side and the variety of options (light / indicator etc.) a bit confusing. It is very useful on the other side that you can adjust the pitch.
