I know these have been discussed before - I wonder if anyone has any longer-term feedback on the Kano pi kits? Are your kids using them much, or do they find once the challenge of building is done, the product is too slow to keep them engaged? Mine (11) has done and enjoyed some coding with scratch & I'm wondering if this is perfect next step or kind of too late. Pimoroni look great too but may require more knowledge/input?
