content: While the finished product--a working phone with see-through cover and flashing lights--is great, this toy is definitely not easy to assemble. It took a bright 9-year-old, her 40-year-old aunt, and the child's grandfather (well-versed in electronics) two hours or more to finally get all the pieces in place! The parts seem to be well made and the phone really *does* work, but the directions are very difficult to understand and there was no explanation whatsoever of how a phone works. In short, what was supposed to be a fun "learning experience" turned out to be an exercise in frustration. This kit is probably best suited for teenagers or adults who already have some background in electronics.
