Overall, it's fine and does the job. But, I was hoping for a bit more immediate response and accuracy. This doesn't seem any better than the Korg tuner I bought 20 years ago. Or, maybe that's a testament to their quality and consistency?
My biggest frustration is that the tuner has turned on inadvertently, 3 or 4 times now. I didn't bump or touch it, yet it somehow turned on and stayed on for who knows how long before I saw the lights. Maybe something bumped the table near the tuner, but I know that nothing had come into contact with the power button.
I'd probably still purchase this over others, based on the positive aspects.
