I like the way it looks, very good build quality, nice finish, very solid feel.
Hardware is pretty good as well, the device is very snappy, no lag whatsoever.
The display is great, bright, good contrast, very sharp.
Has a decent heft, it feels premium in the hand.
The sound is very clear and crisp, a bit harsh sometimes, as expected from ESS, and it can drive most decent headphones (I tried a Momentum M2, HyperX Alpha, Beyerdynamic DT990 250 Ohm and Hifiman Sundara but I mostly use it with Starfields and Mangird Tea).
What I didn't like though, is the software, it has a stripped down ver. of Android 9, which doesn't allow too many customisations. I installed Microsoft launcher and an icon pack but after a couple of days it crashed completely, it refused to charge the battery and the square button that shows and allows closing the running apps, also no longer worked. I had to reset it to factory default.
It did that on me, twice. In the end, I gave up installing customisation software. I just run Spotify and Tidal and basic Google stuff.
What I didn't like as well was that after I stop the music, for two or three seconds, I can hear small artifacts, like small electrostatic discharges and that happens no matter I had it on low or high gain.
One more thing, the indicator LED is either blindingly powerful or completely off, it cannot be dimmed.
