One really cool feature is the "rotate" button (center button on the posted picture). You can clip it to the back of the headstock and then rotate to the display to read correctly from your viewpoint. And the tuner remembers that orientation when it turns on again. It can be easy to confuse the rotate and on/off button by feel on a dark stage, but you get used to that. I use these tuners and like them.
I also have Snarks in various flavors, and my old standby the Intelli IMT-500. Glad I bought a full case of ten years ago, and none have died yet. I keep a tuner in each instrument case, along with a capo, strap, picks, and spare strings.
