What age range is each LINKKI kit suitable for?

The LINKKI Basic Kit is child safe and passed CPSIA(The Consumer Product Safety Improvement Act) compliance test for 6+ yrs old for the US customers. However, the LINKKI Motor Kit includes small parts and an exposed circuit board, adult supervision is recommended for children under 13 yrs.  

When you find your LINKKI construction doesn't work properly...

1. Change the position of joint.

2. Change the position of connection on the circle.

3. Check if you used the right assembly clips for the circle described in instructions.

4. Check if linkages are level. If not, make them so using washers.

5. Use assembly clips of suitable sizes and make connections neither tight nor loose.

6. Change the order of layers if they crash each other.

7. Keep in mind that there is invisible force called gravity that helps or interrupts movement.
