First things first, the small device works fine and does not need to hide from his big brothers. The unit can be left while playing on the headstock, ball joint, it can then be aligned so that you have the display always in mind. The votes of the individual strings succeed right away and even with various background noises, the device performs its service reliably. Another positive feature is the backlight, this also works the votes in total darkness. If the string in tune, the entire display turns green. If you finished tuning, you would need not even turn off the breaker, the unit switches off by itself.
My conclusion: Highly Recommended, for the price makes it really nothing wrong.
