I was a bit concerned when I saw the age was for 14+. However, my 9 year old grandson loved making this sharpener with supervision. The instructions are very clear and easy to follow. A great gift for any curious child.

My grandson loved putting this together and then sharing it with his class at school. He is ten.

This is such an awesome and useful kit. But to be honest, the first kit didn’t turn on despite double and triple checking the connections. Kiwi was very quick to provide replacement motor/battery pack/wires (we reused the bulk of the original parts). It worked great the second time around.

This was a little complicated, very cool and very practical. Perfect for my pre-teen!
