I PURCHASED THIS IS Icstation DIY 3D Xmas Tree Electronic Soldering Assemble Kit 3 Color Flashing LED Science Craft for my grandson to do as a science test with my son, his uncle. The parts are way too many and too small for a 9 or 10 year old. That said, I'll give it tg o my son to put together for a church member as a small token gift at Christmas time. Such a shame as I was hoping this would be a project my grandson would enjoy. At under $10 not a bad buy, but definitely not a beginner's project.
