Rugged and Precise
I have had many tuners and this is my everyday favorite. It is tough by design using a simple hinge configuration with a reversible display which is clear and bright. I find it more accurate than the Snarks I've had. I put both the Korg PitchClip and the PolyTune Clip On together on a guitar to compare and they read exactly the same which is excellent in a moderately priced tuner.
