The device is very small, which readability but does not detract. Once selected the correct setting for guitar, Ukule, violin and bass automatic detection for the ailing side works very well, the voices makes no problems and is compared with my old tuner with analog pointer more quickly and accurately by hand. Whether the device also meets professional standards of accuracy here, I can not judge from layman fully meet the requirements sufficiently.
Even considering the price a strong buy recommendation. The included user manual in English only, with the ease of use is not a problem.
