13-in-1 Solar Robot Toys for Ages 8 9 10 11 12 Year Old Boys Girls, STEM Science Kits for Kids Age 8-12, Building Experiments Robotics Kit STEM Projects for Kid Christmas Birthday Gifts (Gray)

While it's hard to assemble (too many pieces for the lower end of the recommended age range) it's well organized and a great gift for my grandson. There's no charge in the solar cell when you open it. But my son had a great time helping to assemble it.

This was a Christmas gift for my then 11-year-old grandson this was from last Christmas he was very excited to get it and work through it he has several that he's gotten the past two Christmases all from the same shop here on Amazon that sell complete kits no pieces missing always very reliable easy to put together for some people

We really liked that it came with little bags and labels for the parts. Our solar panel did not work, thankfully there was a battery option. :) So far, we only built one of the 13 robots.

Buen juego

Him and his dad worked on it this weekend and he said it was fun.

La verdad es que el robot solar Dioju no cumplió con mis expectativas en absoluto. Desde el primer uso, me di cuenta de que no era tan funcional como prometía. La calidad de los materiales se siente inferior y el ensamblaje es complicado, lo que lo hace frustrante para los niños.Además, el rendimiento del panel solar es decepcionante; no capta suficiente energía para que el robot funcione de manera efectiva. En resumen, no lo recomendaría, ya que hay muchas otras opciones en el mercado que ofrecen una mejor experiencia de aprendizaje y diversión

This was a gift for a friends son.. He was most anxious to learn about solar power and its applications. So many variations to make.Yes, it was a happy birthday! Highly recommended for a youth in the age range who is curious and creative.

I gifted this to my nephew and he loved it. I would recommend to anyone who wants to gift to any child of 8 to 10 years of age

ソーラーパネルによるモーター駆動は問題ありませんでしたが、モーターとギヤを固定するプラスチックの型の品質が悪く、固定するとギヤに負荷をかけてしまい、モーターが回らなくなりました。

Remarkably complex, very poor instruction manual, flimsy and fiddly plastic pieces that don’t stay in place. Don’t buy.

バースデープレゼントとして購入しましたが、この箱ではできません。箱は大きい箱で発送したではなく、袋積みで送ったので、壊れました。中の部分はだいぶ大丈夫そうですが、一つのパーツはぎりぎり壊してない(写真で黒パーツ)。セールで買ったので、残念ですが、バースデーにはなく、いつかで作ると思います。
