Having tried a couple of other floor tuners in the past, I needed something with a bigger display. Korg is a well known brand and since I still have a tuner since I was 15, now 40, I can verify the quality! The following are from my perspective as a hobbyist guitar player. Pros: Standard size for those who are into it. Big bright display with large letters, can be seen from International Space Station, so no more excuse that I don't see well! The feel of switch is as soft as I want it, without making so much noise when activating. The additional feature I like is the output power, so I can power another pedal from this little fella. Selectable true bypass or buffer. I always leave it to buffer as I connect about 8 pedals after it. The operating modes are subjective but for sure you will find the one you need. I find mirror not so useful for example, so I stick with strobe. Cons: If I can think one, that would be the gloss finish that leaves fingerprints all the time. I consider it minor.
I didn't find any reason to go with something more expensive like peterson for example, so I find this one to perform well, can be seen quite good. I would recommend it if you have space for a standard size tuner.
