The best tuner available. I've had one for a year now. Works grea,t quick, versatile, and extremely accurate. The clip grips well and stays on when placed securely on my tele. The housing is high grade plastic; however I recently broke the arm between the display and clip. Peterson shipped the new part within 2 days. Also, make sure to cut the unit off. Auto shut off doesn't work if the unit is at all vibrating.
