In a world full of of poorly designed and built throwaway items, this Korg tuner seems as if it were designed by folks who wanted to make something intelligent and functional instead of flashy. It is well made with a nice LCD screen so the 2 AAA batteries lasts a long time. Aside from that it just works well. In addition it is not expensive. I would also check out the option of its bigger brother, the 60, which has a screen light and a metronome for a about 10 Euros more but on the downside has a less legible screen. I am very satisfied with the purchase.
