As someone who loves hands-on STEM projects, I was excited to test the Poraxy STEM Kits with my 9-year-old nephew. The variety of 6 different builds (solar car, wind car, obstacle-avoidance robot, etc.) immediately caught our attention - it's like a mini engineering bootcamp in a box!

The Good: These kits deliver serious educational value. Watching my nephew's face light up when his squirmy robot finally came to life was priceless. The projects teach real physics concepts (like solar/wind power) in a tangible way. I particularly appreciated how each kit is individually packaged - no chaotic piece-mixing disasters!

The Challenges: While marketed for ages 5+, be warned - these require serious fine motor skills. Even at age 9, we encountered frustrating moments like gears not fitting perfectly on motor shafts (bring your patience!). The solar car gave us the most trouble - we eventually had to modify the design slightly to make it work.

Parent Tip: These are absolutely parent-child bonding activities rather than independent play. Set aside quality time (with snacks!) for building sessions. The included screwdriver is cute but flimsy - having real tools handy helps.

Final Verdict: Despite some assembly frustrations, these kits spark wonderful "aha!" moments about engineering principles. Best suited for patient kids aged 8+ with adult support. At this price point for six projects, it's fantastic educational value that beats screen time any day!
