In practice, it has then but proved too slow and not really accurate. As someone has already written to the (deep) E string can not agree on the green point! The display will remain a point to red - either over it or under it. I did not know of other tuners!
The other strings have lasted much longer than, for example, with the Snark (the 20, - costs).
Not all strings could be votes on the green dot.
(My guitar is in the 400 - range - because it is so not.)
So I'm with "hand" faster than with this tuner!
A little awkward, I find that you can not rotate the display.
If anyone is interested. The company can KORG (from Japan) produced the tuner in Vietnam.
Conclusion: Not for people who want to tune your guitar quickly before scheduled in loud places!
Addendum: I give instead a star now 2 stars, because the control with a BOSS tuner (99, -) showed that the strings were in tune except the low E string and the B string, but only minimal was wrong ,
