I use it since April 2010.
I bought it because offer at an English merchant.
It is very readable, even in bright sunlight. The display is large, bright, and we can choose the display type. Either the light bars are tightened to the center or a scroll faster or slower, depending on the difference in pitch.
BOSS great light illuminates the back of the unit (which can remove). Moreover, there are plenty of function you can set yourself.
Great price / quality ratio, considering the price I bought it.
