Liebherr R 9800

I was stunned to see the size of the box and its weight. I sorted all the bags by number and started the build. It was great to build, but you have to look very carefully at the instructions as some are a little vague as to parts placement. I loved the play aspect and the new control system works great. As said before look very carefully at the instructions. Thanks, guys for a great build. Would love to see the Liebherr dump truck for mining. more less

LEGO Technic 42100 Liebherr R 9800 Excavator brings the whole LEGO Technic theme to a brand new level. The possibilities of the Powered Up motors and smart hubs and the functionality of the Control+ smart app are simply mind-blowing. I guess this is the first LEGO set I'm reviewing that I didn't get bored playing with. more less

The Liebherr R 9800 is a robust-looking and thoroughly detailed toy that is not only a true joy to look at and behold, but also the uttermost fun to play and experiment with. This set demonstrates the almost endless possibilities of the new Powered Up System. [...] Because it is unparalleled in the Technic line-up I highly recommend it, if you can get over the steep price. more less

42100 Liebherr R 9800 is a big, beautiful and expensive set. But, it's entirely dependent on the smartphone app which will not please everyone, and may well give many a reason not to buy it. However, I believe it was absolutely the right direction for LEGO to take its technology platform because it opens up so many possibilities. more less

In my opinion you get a great looking model, a decent building experience, awesome hardware (bricks, motors and hubs) and great value for money. The half baked playing experience with the app invites you to craft a real good working controller yourself, and if you get that working, it even open ups the great world of Mindstorms like robots in an even more serious way. On an Arduino or Microbit you can code in C++ or Micro Python instead of LEGO's own crappy visual block programming. more less
