Sounds and plays great, like a real SG.
However, in my case, it required a full setup (neck relief, action, intonation) as the neck was loose and the action out of the box was over 2mm on the top and bottom strings. After the setup, it's almost as good as a Gibson.
It has some minor cosmetic imperfections like a wobbly pickup selector switch in the middle position or neck binding not aligning perfectly with the nut. Frets could use a bit of filing at the ends, but it's not terrible and absolutely OK to play the way it is. The finish is perfect, with no scratches or anything whatsoever. Sometimes, I can hear some rattling noise coming from either the bridge or from under the pickguard, probably caused by a loose pickup wire or (I presume) cheap factory strings, so it's an easy fix.
Overall, a great guitar for the money, I recommend it 100%!
