We bought this jigsaw set a few years ago when our son was about 2 years old. It was his first jigsaw puzzle. He loved playing with it repeatedly. It captured his attention with its transport theme. The pieces were nice and chunky to make holding and bringing together easy. And because the puzzles are only two or three pieces each a child can quickly get that sense of achievement of seeing the finished picture. As he got older he began asking questions about what each vehicle did.
I would very much recommend this puzzle for young boys and I am returning to this product to buy this as a present for my nephew.
In general, I find most Orchard Toys products well thought out and innovative.
