Item received today. Really device very VERY easy to utiliser.Vous place it on the handle side has a bit of your instrument setting screws (for me it's the ukulele). Among the two buttons on the side: The first button when you hold the tuner face has to read it, is used to choose which instrument you settle (but aussiil serves to extinguish it with your finger press longer). And then remains to play each string. And as the tuner recognize the string you do, it displays the letter and number one: just have to settle for the amperage is in the middle (btw it turns from blue to green when. his is right). Frankly simpler than that it 'is not. I am often kind gogole I had no worries. So go darken not need instruction in English, just a little observation.
