This tuner works great. It is precise enough to adjust intonation. The display is very nice, with choices between a "normal" and a "strobe" setting.
I also like that this tuner doesn't have lots of options that I don't need, like a metronome, or test tones or settings for different historical temperaments or "sweetened" tunings. The less things that can break, the better.
The build quality does feel very cheap and flimsy though. Only time will tell I guess...
Ideally I would prefer to have a tuner with a needle, but the only one I can find these days is the Korg OT120, which I have found to have HORRIBLE build quality (I've had two of them fail within a couple of years). I hope this offering from Korg will last longer, although I am a bit concerned about the seemingly poor build quality.
