Overall, this is a good one.
The tuner is pretty accurate and precise enough to be used when playing with the band, at least to my ear.
It has a huge and bright display that you can read from any angle and from a considerable distance, which is a good thing in the studio when your mates have none or use clips since you can lend them your tuner for a second.

It still has a downside, though. The buffered mode turned out to be too noisy, at least for my setup, which is still alright-ish since you can switch to the bypass and forget about this at the expense of the not-too-loud pedal switch.
