The good: printing quality on the pieces was excellent. ABS molding was fairly precise; there aren't noticeable gaps from slight size variations. Instructions were clear and in color. Shipped immediately after ordering and took only a week.

The bad: stickers were printed on white background, instead of transparent, which made many ugly and unusable. Plastic colors were not consistent and did not match Lego branded blocks (too green). Hinge prices were very difficult to assemble and do not move easily, which is important when the set has dozens of them. A couple parts were incorrect but or missing: Nick's ruff was replaced by the fur collar. A couple minifig hands (nougat color) came as unformed pellets.

Overall, the product was good but I regret buying it because of the missed details.

I've only built a quarter of the tower, but everything is going together very nicely. The stickers are a bit off in color, but nothing that takes away from the build. I'll definitely buy from joy bricks again.

The quality of the bricks is very good. Only a few joints and hinges were a bit difficult to assemble. It was particularly good that only a single piece was missing. Fortunately, it was a standard part and not a rare one. My biggest criticism relates to the stickers. They are printed well, but unfortunately, they are white in areas where they should be transparent. That doesn't look very nice, and the Gryffindor flag suddenly turns yellow/white. The figures are great. For the money, it is an excellent set."
