    Impressed with the booklet

    The booklet that came with the flashlight explained everything really well - like what's a capacitor? Make more like this!!!

    My 9 year old did it on his own

    My 9-year-old son was able to assemble most of it on his own. We did have to trouble-shoot the bread board a little bit, but figured it out pretty easily due to the diagrams in the instruction book. My son loved the build, and is thrilled to have his own hand-crank flashlight. Not sure how sturdy it will be over time, but it seems pretty good now.

    Great for groups

    We had this as a project for the 7 and 9 year old during the holidays. They had help from their older cousins. It was a great group learning experience and the kids really liked the end product.

    Perfect for our kids

    Everything was labeled and packaged. Instructions were super clear, and it was fun and educations. We could do a quick easy assembly for 4 year old level and then a more detailed educational assumbly for a 13 year old. A single piece for the stickies on the flashlight window might have worked better.
