Might as well use a Geiger counter

Tried this on a few instruments - piano, violin, guitar. Played with the settings. I know the piano is tuned. It says the C is a D#. As the other reviewer said, it takes too long to track a note.

I actually paid for this. Learn from my mistake. Find something better.

Poor response

Way to slow to track to note. Useless for most instruments. Don't waste your money on this.
