I bought these jigsaws for my son (2 years 3 months) and they have been a big hit. He loves to choose which dinosaur to do next, and likes keeping each one in a section of the box. When I first opened it, I was a little concerned that it seemed a bit flimsy, and the box didn't look very smooth, but once we got into using them, these jigsaws have stood up well to use, and fit together well (some puzzles slip out of place). The pieces are a good size for his hands and after a few weeks, he can do all 4 without any help, and takes a lot of satisfaction in finishing them. Also not too huge, so will be a good size to pack when we're travelling. Nice bright colours, and the pieces have shape codes on the back if you ever get them muddled up.
