Just Awesome
on October 15, 2019
Posted by: LEGOcreatordudes
Everyone should have this set. Why? Because the functionality is perfect. The app works awesome on all my different devices. The app is responsive. And I love all the details. And let’s not forget that you get 7 motors and 2 very cool smart hubs. So I love this set. BUT. I have seen some reviewers that say that you can’t make any custom LEGO sets due to the fact that you can only control the two sets that are currently out. I just got an email back from LEGO. And they said that you will be able to make custom sets using the app and the motors and other stuff in the beginning of 2020. (You will also be able to buy the electronic components for individual purchase as well).
I would recommend this to a friend!

Best build so far.

The LIEBHERR is a challenging and fun build. I enjoy watching the pieces develop into parts and the parts developing into the build.
I really liked being able to verify your gearing is correct and working before moving on to next section.
This was a fun project and can't wait for next large TECHNIC release.

This set is very rewarding once complete and working properly. Make sure you complete it before testing it,or try connecting it to the app... the only thing about it is it moves very slow,but i can imagine the real thing would be slow moving for what it is.the only thing that i wish this set had was the rubber track studs from the boost creative toolbox set 17101 to help it move better on hard surfaces.other than that,awesome set! (Works with Samsung Galaxy Note 9)

AMAZING BUILD
on October 28, 2019

I have just finished building the Liebherr R 9800 Excavator and i have to say that it was a pretty challenging build with the new hub and motors. i had no problems connecting the hubs with my phone during the test mode.i have built a quite few other Technic builds like the Volvo front end loader the bucket wheel excavator and many others. WOULD LIKE TO SEE A MONSTER ROCK TRUCK TO MATCH THIS SET I WOULD DEFFENTLY GET A MATCHED SET

Good, could have more

The whole unit itself is amazing. Nice toy to play with, if you want to "attack" your other Lego sets :))
The only small issue that i could find at this set, it was the tracks - they are a bit loose and by that, the whole unit moves a bit slower.
It's still awesome. Thank you Lego

Love my Liebherr & Volvo
on November 26, 2020

Everything works fine as well as no problems with the build ! Love them both ! Hey Lego, can you built a model with Caterpillar or John Deere branding? We in the USA are big Lego fans and we can associate with that more than Liebherr (but we know Volvo cars mostly, not construction equipment). Great fun overall !!

Great Set!
on October 16, 2019
Posted by: Fettfan
The biggest thrill to me with legos is the actual build, and being a challenge....Its like a puzzle, sort of....and this set does not disappoint....I love the number of pieces and the sheer size....and I'm only 3/4 of the way done....
One comment to Lego: PLEASE do a technic set of the Caterpillar mining dump truck in scale to go with this kit...There is a custom one floating around but no lisenced kits....

What a monster!

Not only is the build fun, but the play factor is just as fun with all of the motors and functions of the final product. The hubs connect well, and have only had minors issues with the tracks slipping while driving on carpet
