Great model to build, instructions are clear and easy to follow the only problem we found was in testing 2nd stage was, you need to have all the motors connected, but this was a minor glitch. 

The down side we came across was, missing pieces, in bags 1,2 and 3, so needed to wait for replacement parts to arrive before we could complete.

Great Build

LEGO

I loved building this set.

It took just over 20 hours to build from start to finish. This included sorting all of the pieces out before starting to build each section. This is something I always do as it makes the finding of pieces easier later on.

I had no problems with the setup and control of the motors using the Lego Control app and everything functioned as it should first time through testing. 

The control and functionality offered by the app is really great and something that I felt was lacking from the Bugatti build.

A challenging and interesting build

This Liebherr is just perfect, it exceeds my expectations by a lot, having a lot of big tech model I was hoping to have a high level of challenge, mission accomplished this is not a model bought if you are beginner because it is very complex and hyper well done, with the application I am surprised of everything that can be done with, the application is intuitive and proportional so a very high level of precision in the functions I loved the hours of this gigantic kit and highly recommend it

Exceeds my expectations

To anyone who is thinking about buying this set. I say to them. BUY IT!!!!! I love the details put into this set. And the functionality is great. Everything works so smoothly from the app and everything. ALSO!!! To anyone who is having trouble with the step two smart hub testing process. When you do that. You have to have all of the motors connected to the hub in order for it to connect to the app. And after you are done testing. You can take out the extra motors you just put in. And continue building. I hope that this solved the confusion, because I really don't like seeing bad reviews on a LEGO set.

BEST SET EVER!!!!!!!!

I have to say the LEGO Liebherr R 9800 Excavator Technic 42100 build was pretty fun build. It was challenging, but not too challenging where it causes too much frustration. The only slight complaint that it is a bit on the tad expensive side, but being a LEGO fan it's still worth it. I thought I had a missing piece, but found out that I had accidentally started building the last part before I was finish building an earlier section. I guess that is how eager you get to finish the build. This is my second Technic build, but not my last as I bought the Volvo hauler as my next build.

Second Technic Build

Jane

An absolute pleasure to build, and operation of the set is flawless. There were some challenging moments, such as routing the motor wires is often hard to see. 
The only complaint I have is the App. There are 4 orange buttons, and if you accidentally hit one, it prompts you to set one button actions, and once you hit that button, you're stuck in a loop of trying to set the things up with no way out. I find myself just exiting the entire app and restarting everything. 

Pictured is my Liebherr with a few more hours of build time remaining. The bucket is the last thing to add. 

The controls are great as they allow feathering of each movement, so fine tuning the rotation to be perfectly straight is easy. 

All and all I very much enjoyed this build. Every time I buy a very expensive set such as this, I fight with myself over whether or not it's worth the money. Taking into consideration the people who thought this up, built it, tore it down, documented where each and every piece went, and drew up incredible instructions, I have to say yes. The quality of each Lego part has not changed over the last several decades, and that is a wonderful thing. Once I get my hands in a pile of parts, I know it was worth every penny.

Liebherr

My husband got this for him to build with our two sons, however our oldest son (12) did most of the work lol
It took roughly 3 days to complete as they only worked on it for 2 to 4 hours a day but enjoyed every min of it. They were a little disappointed when they completed it so I may need to get them a bigger, more challenging set in the future :
;-)

Father - Son building time

What an incredibly fun, challenging build this was!

Directions were extremely clear - at no point did I feel I was flying blind. When things didn't work or fit, it was inevitably my mistake. Figuring out those mistakes was part of the fun. 

Mid-build Bluetooth motor testing went perfectly. I had a couple of issues with a previously-connected power pack having problems reconnecting, but that was because I exited, but did not terminate, the Connect Plus app. It was easily fixed by taking out a battery and, essentially, rebooting the pack. 

When all was done, the last test - the moving of the scoop front to back - failed. I heard the ending purring perfectly, but the gears and scoop did not move. I figured out that I didn't put one key dowel into the red motor input (I accidentally put it in a hole just to the side), and with very little deconstruction got it in the right spot. 

That didn't end the problems - the hinges that connect the front scoop panel to the motor/gears were connected wrongly. After about an hour of trial and error, I finally got everything in the right spot, successfully calibrated the unit, and I was off to the races.

I hope this doesn't sound like a criticism of the set - as I said, every error was my own fault, and it was a sick kind of fun figuring out every which way I went wrong. When the unit finally worked perfectly, it was incredibly gratifying. 

I will say the Bag # 5 set of parts (the last stage of construction) was a little tedious - lots of ladders, lights, trim, but I do have to say the once it was done (after about 90 minutes of work), all these little bits added up to a better-looking, more realistic excavator. 

I haven't played much with the set other than to test out what it can do, but that will come, now that I finally worked out the bugs. 

Bottom line: I absolutely LOVED this build. It required a level of focus and attention to detail that I found very, very rewarding. 

This takes the place of the Roller Coaster (10261) as my favorite build. I can't recommend this any higher!

Everything You Want From a LEGO Build

The build is not the most pieces of any set, nor is it the most complex, there were no real problems building it and it was pretty straightforward. The only problem I had was solved when it turns out you ned to have all motors connected to the second hub to test it. This is not in the instructions, but calling support they are aware of it and just plugging the motors in will allow you to test part two.

The thing is pretty heavy, the bag of 100 "rocks" is a good touch and it is how the LEGO group is able to claim that this is the largest set by piece count. Those pieces are not in the model unlike the rough terrain crane so I don't count them.

When playing with it, make sure to stow the steps and lock them in place, I did not do that originally and caught it in the carpet.

The controls are well explained and the app works fine on my phone. The model is very smooth compared to most power functions sets as there are not a lot of complex gears in the boom. The boom and bucket are all moved by linear actuators. The new longer linear actuator is soing to be something to play with in the future.

All in all, a nice build, fun and heavy. Lots of replay value. Most of the expense is in the electronics and the license I suspect. But it is really fun to play with.

Better to play with after it is built

Emily

Excitement quickly turns to disappointment. When I first saw this set, I was very excited to build and share this experience with my young grandson. My grandson loves “diggers” as he calls them and was very excited to help grandpop build this set. Although, too young to build this set himself, I built the set completely, then removed a few pieces so we can complete the set together. 

The positives with this set are few compared to the negatives in my opinion. The set is large, well designed and interesting to build. The control app works well when used with a tablet. I made sure all motors were connected to the Bluetooth controller before testing which worked well.

On the minus side is the set was missing parts to complete the build. The parts missing were cosmetic and did not affect the function of the build. Lego, please don't tell me “Usually they're found stuck in the packaging or hiding on the floor!”. I can assure you they were not included in the set. Stickers on a high-end set like this; really? What good is a set like this if you cannot play with it? The drive system is significantly underpowered. The loose-fitting tracks only add to the issue, jamming frequently. The model is easily impeded by short pile carpeting as the drive motors strain in agony. In my “play” case a couple of corks stopped it cold when I was trying to pick them up in the bucket. The boom, dipper arm and pitman arm work well, however, the bucket closure drive train over travels and the application is unable to calibrate for the situation.

My wife watched as we played, then asked the cost of the kit. I answered her question, she paused and said, next time, just put the money into his 529 plan, and she walked away. A smart woman she is.

Excitement quickly turns to disappointment.
