Korg OT120

I purchased this orchestral tuner to try tuning my upright piano. This Korg seemed to be the only option as I could find no alternative products in this class.
The reality is that the tuner presumably does its job reasonably well, although it does not detect sounds in the far bass and far treble octaves of the piano.
Also, I was quite utterly disappointed by the build quality of the device. It is made of cheap plastic and is very, very far from feeling "solid". All the switches and buttons are very wobbly and unpleasant to touch. Overall, it feels so much different from the sturdy construction of Korg's guitar tuner pedals.
Frankly speaking, it is a big disappointment.
