I'm not satisfied with this product as it fluctuates a lot when tuning. I can't be sure of the tuning because if I tune one string, and then check it at the end, it's either -7 or +7 cents. It takes a long time to tune, and in some situations, you don't have five minutes to listen and be sure it sounds good. This is for the acoustic guitar. Sometimes it doesn't identify the notes in chromatic mode or instrument mode. The biggest deviations are with the bass guitar. It doesn't identify the B, E, and A strings: The B string gets worse out of tune if I go by the C and C# it shows me. For the E string, when it shows something, it shows D -29. The A string never (it always tells me C 50+). It only picks up D and G, and then the notes at fret 12. It's not worth the money for the bass guitar (even though it has a dedicated mode for it), nor for the acoustic guitar. Better to use an app that shows you the frequency because it's the same thing (in my case, for bass, I track the frequency and tune it in less than a minute).
An extremely versatile digital tuner. The internal battery lasts long enough that there's no problem. The fact that the battery is built-in is the main advantage because you're no longer tied to the short life of LR or AG cells, which you can't find in every store. With this product, you can charge it at home with any mobile phone charger. The display is easy to read and the menu is simple and intuitive. It's suitable for all musicians, from violinists to timpanists, as it easily detects extreme frequencies. The clip-on microphone can be easily attached and allows reading the display in almost any mounting position on instruments due to the multiple connecting hinges.
