    5.0 out of 5 stars Excelente modelo LEGO
    Reviewed in Mexico on April 12, 2020
    Un producto de LEGO como ninguno. Su calidad es notable desde la caja en la que vienen todas las piezas. 6 kilogramos aproximadamente de pura calidad. El modelo en sí es altamente recomendable para constructores LEGO avanzados y/o para aquellos que buscan un reto. Por el precio que pagas, obtienes además de las piezas para el modelo, 2 Smart hubs, y motores que puedes utilizar para MOCs (te sugiero la app Buwizz).

    Armar el modelo es un reto, empiezas primero por la estructura con las orugas, después la estructura superior, luego el brazo y finalizas con los detalles súper minuciosos que son gratificantes cuando ves el resultado final. La app LEGO technic (sugiero veas compatibilidad en la página de lego) funciona al 100%. Conforme vayas armando el modelo, el instructivo te mostrará cómo realizar las pruebas durante el proceso de armado y concluyes con la calibración del mismo. La app tiene retos para entretenerte por lo que además de que se ve genial como trofeo en casa, tiene jugabilidad. El único contra que le pondría sería que para jugar el modelo ocupas de manera obligada tener la app en tu celular y que los Smart hubs tengan baterías (12 baterías AA), ya que de lo contrario el modelo no lo podrás cambiar de posición una vez lo hayas concluido.

    En conclusión: por lo que pagas obtienes un gran modelo, muchas piezas si te gusta armar MOCs, Smart hubs y motores.
