Got this for my active grandson. Never seen him so focus working on this kit. Endless hours of creativity. Worth every penny. This is one ' toy' this grandma will support.

Fantastic Idea with QA/QC Issues
So, we love them. The kids love them. But the frustration when the connections do not connect due to QA/QC issues or the wires break because QA/QC issues are very frustrating for the learners and the parents. We look forward to those issues being addressed.

Great tools for expanding play and practicing many concepts
We love our SparkBlocks! My 9 year old now knows more about electricity than most adults! We did have a few minor issues with incorrect instructions, incorrectly labeled pieces, but all were updated on the online editions of instructions and troubleshooting pages. I'm excited to see how they improve and expand the next edition of kits.
