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.

I found this one harder than the Mari one, possible because of the similarity of colours. It's a bit more of a puzzle to put together because of that.

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