Before judging a resonator guitar, we must understand/accept that this type of guitar is by design a picky/demanding instrument. And in this case we have a relatively cheap instrument.
The appearance of the guitar is quite good, the materials seem of quality and the workmanship and finishing are acceptable. (When I opened the box, I did not find any label regarding the manufacturer and model anywhere, nor any quality certificate.)
The sound of the guitar is pretty good, although not very balanced across the entire fingerboard (for strings 4,5,6, the wound ones, the resonator-cone responds more and more attenuated towards the bridge). The sensitivity to the player's interaction is good, but does not excel. The bridge/saddle is not positioned precisely enough, and thus the musical notes played along the strings become increasingly out of tune as we approach the bridge.
The frets are unpolished, so they produce a scratchy sound when using the 'bend' technique.
The strings that the guitar arrived with are of poor quality, including from the perspective of the grating sound caused when using the 'slide' playing technique on strings 3,4,5,6 (wrapped/wound strings).
For me, the slightly larger neck width (44.5mm) and the glossy surface finish are particularly appreciated.
In conclusion, the guitar is good enough for familiarization with the 'resonator guitar' genre.
