Good quality for price. Handle feels and looks cheaper then others xinzuo knifes. Knives balance is blade heavy on bigger ones and handle heavy on 3.5 and 5. I would prefer balanced chief and 7 inch one. Out of box sharpness is good. Steel is more soft then 440c and gets dull pretty fast, but it really easy to sharpen. If you want full set for decent price buy it. Otherwise I'll look for better quality single knife offers.
I can recommend the seller: fast send from the store, fast delivery to Ukraine (through Netherlands). But I can't recommend the knife. First of all, handle stinks terribly, and after week of usage and washing, it haven't removed completely. Another problem: spots of rust appear if you don't wipe it thoroughly after the washing. Rough side of kitchen sponge removes them so far. It weird though, because knife I bought from this store before (another model, chef knife) doesn't have any problems. And items' descriptions and stamp on the knives say that it is the same type of steel.
