This is a very good toy for kids. I was originally introduced to Knex products at my child's day care where I watched my 3 year old having a great time building shapes, forms and figures with Kid Knex. Attributes that make this product a winner include:
* Interesting shapes
* Fun assortment of colors
* Parts snap together and apart easily
In addition to these attributes the Knex products help develop creativity and hand-to-eye coordination in children. Also the toy seems well constructed. The pieces are durable with just the right amount of give so they will last a long time. More importantly all edges are well rounded so there is nothing sharp. Lastly the product comes in a nice easy to transport carrying case
This product seems age appropriate for kids 3 plus. It should be noted that this product includes small parts that might be dangerous for children that are younger.
