This is one of the best clip on tuners available today. Unlike others of its kind, it can angles in any direction you want,. Also the button is in the right place right on the face. Other tuners have the buttons on the side which is a bitch to navigate at times. I have a few different ones and will be doing a review on them all and showing how this guy beats them all. It folds in flat so you can leave it on even in the case..the big round most popular one (rhymes with shark) sticks out and is bulky.. If you want streamline and great operation, This is the one to get.. My suggestion get a colored one so you can find it in your gig bag in the dark. Sure the black ones look cool but disappears in a bag of cables and gig stuff. Battery life is good unlike others I have and its easy to read and operate.. You won't be sorry.. Tune up and get down.
