    4 out of 5 stars
    A (Mostly) flawless product.
    In the end I was able to build the model, and the design is well done and fully functional.However, there are several key points, both good and bad I should mention:I love the change lego has made on the control boxes, not needing to have a screwdriver to open the thing makes the utility of itas a toy MUCH more enjoyable.I cant really expect perfection in the field of functionality its generally impossible, being made from a universal building kit. mechanical drift will happen, steering can become off, creating a slight turn. While I am not expecting better quality, as it is at its best at the moment, it would be an interesting study for lego to do to improve on that factor.Last but not least, a sad note to mention, despite legos focus on quality, I DID get a defective part. In fact, the first part I pulled out has a semetrical cave-in defect in the pin holes on opposite corners of the box, as seen in the photo, its hard to see but its real. Those holes are essentially useless and I couldnt use it as directed, I had to swap it for another one from further down the instructions.So... while I do believe the product is worth it anyway, It deffinitely had its quirks and the buyer should keep itin mind when buying.

    This lego set was exactly what he wanted. It was a fairly challenging, but not impossible lego set to assemble. He enjoyed the challenge and was proud when he completed it.

    Additionally, when he was done, we connected his android device to it for remote control and he has enjoyed hours of running it around the house and using the well designed shocks, can run over obstacles and climb different terrains he has made. Good product, well done!

    My husband loves Legos!!! And this set did not disappoint. He commented that the set was easy to drive, solidly built, and had lots of fun details. He also thought the app was great! Legos are the best toy ever developed, whether my baby grandson playing with the large chunky Duplos, or my 50+ husband playing with sets like this one.

    I wanted to have something to do while it was cold out and this fit the bill! Fun build which took me about 1.5 days to build. Instructions are clear and the packaging makes it even easier to follow. Enjoy your build!

    Bought this for my middle son for Xmas. He'd had a stroke last March and drs thought doing something such a building with Lego's would help his hand/eye coordination. Works like a charm and my granddaughters love to race it around their home

    Es el primero LEGO Technic que armo, por lo que su construcción tomó más de lo que había visto en algunas reseñas. Lo adquirí en oferta a un muy buen precio tomando en cuenta las funciones Control+ con las que cuenta que son 3 motores y el Hub de última generación. La aplicación para controlarlo es muy fácil de usar e intuitiva, además de tener un modo guiado para ir cumpliendo desafíos a modo de aprender a utilizarlo. También muestra en pantalla el nivel de inclinación en ambos ejes y para esto, llega un punto donde si está muy inclinado o le falta potencia, no avanza ya y aparece un aviso en pantalla. En general me parece un muy buen set para uso o colección.

    I am a long time lego fan and have just recently started building the Technic sets. This was my third big technic build and the first with this power system and I love this truck. I did do a little gear swap and now have it climbing 41 degree slopes on smooth cardboard. I am going to try it on more surfaces but I am blown away by how easy to control and how much fun this build is.
