I enjoyed putting this together, harder than you might think given the size but not a major challenge. The pieces fit together pretty well (not quite as solidly as say, Ravensburger, but pretty good), certainly well enough to not compromise the quality of the image.

Having just finished the Rei one I'm about to star this, I've got no doubt it will be as good as the other two in the series.

Also comes with glue for fixing together, if you want to.
