Seemed to be easy to use. I took it out of the box, clipped it to my guitar, gently adjusted it to view the display and it broke. The ball joint where the tuner connects to the arm of the clip if defective. Tried to return but was told it is ineligible to be returned. Waiting for further assistance from Amazon. Very disappointed!
Amazon responded quickly and is refunding me the amount of my purchase. Thank you customer support!
