Extremely complex and slow build, with a gear system prone to fail. The gears keep grinding out of nowhere with all the steps followed. The tracks and the rotation are manual and the boom is extremely slow. I had a lot more fun building and playing with the 42042 set.
No, I would not recommend this to a friend.

Hi, thanks for taking time to leave us feedback, I'm sorry you didn't enjoy the building and playing experience of the Volvo EC500 Hybrid Excavator. We'll pass your comments about the gear system and the tracks to our design team to help with future sets!
The set was fun to put together, and the instructions were well-done. My big complaint is that the motorized movements are extremely slow, to the point that it’s only really good as a static display. For the price I would expect a lot more, and for the swivel and tracks to be motorized. This is probably the most disappointing set that I’ve ever bought for that reason.

I bought this set for my birthday and I absolutely love this set. After reading previous reviews of this set I was pretty skeptical but I bought it anyway. This was my first 18+ set and I love it. It may be a little slow and expensive but if you love all things construction related you should like it.
The build was okay but for the money this Lego doesn’t cut it. It never worked properly and was just an inferior design.
I have built several dozen Lego’s and this was the worst one hands down. Very disappointing

Thank you for taking the time to share your experience with us! We're sorry to hear that you didn't enjoy the build. If you found The Excavator didn't work as it should have, something may have gone wrong during the building process. If you'd like any further help, please don't hesitate to get in touch via LEGO.build/Service and we'll have a look!
Read reviews after purchasing and I was a little concerned. The poor reviews were a bit surprising considering the reviews of the other products I have purchased were so high. I’ve read the negative reviews and my experience doesn’t reflect them at all. I’ve done multiple Technic builds and this was on par with all of them. During the build I was waiting to run into issues that would, in my eyes, justify the poor reviews but I never came across them. It’s not cheap but definitely worth the money and I would recommend.
An enjoyable built with a disappointing end result

The final drive ratio kinda ruins anything that could potentially be enjoyable. Really not much you can do with one motor. Really expensive for what you get. Not sure why they'd even produce this one
