String action was way to high, ground down saddle 1,5mm. Saddle is made of bone so pleasently surpriced there.
There was a bow in the neck but easily adjusted with truss rod which also lowered string action a bit.
Corners on the frets were somewhat sharp but easily filed smooth. They also needed polishing.
Nut needed to be filed a bit, it had sharp corners and strings were caught in the slots. Also made of bone.
So after one hour of work it plays like a much higher priced guitar and has no flaws, intonation is close to perfect on all strings and no fretbuzz.
And in this price point one must expect to do some work on the guitars. So I am overall very satisfied with this one.
