Hydraulic Robot Arm Kit

Before buying this, I was hoping for a solid educational toy to introduce my kids to mechanics, and it delivered on that front—they loved the hands-on building process and seeing it in action. After assembly, though, I noticed it's not as durable as I'd like; it works fine for light play but might not withstand rough handling. The hydraulic system is a neat feature, but it's basic and could be improved for smoother operation. Overall, it's a decent kit for learning, but don't expect high performance or longevity. I'd recommend it with caution for families with younger children who might be gentler with it. :)
- Pros: Building this kit was incredibly engaging and educational, most likely sparking curiosity in my kids about how things work. The manual is useful and clear, making assembly straightforward even for beginners. It actually picks up and moves objects, which is a fun demonstration of basic principles.
- Cons: The materials feel a bit flimsy and might not hold up well over time, especially with multiple kids using it. Some parts were tricky to fit together perfectly, which was frustrating for my perfectionist side. It doesn't have a wide range of motion, limiting what it can do.
