Average rating5out of 5 stars5.0Love large toys, this is a must have.
I would recommend this to a friend!
If you love large toys, I highly recommend this build. It's a Great build project, not only because of the high piece count, but because it's so involved. Great job, and kudos to the engineers on the design. It is so realistic. I also love that you can control this unit from an app. Many hours of family fun in your future. I do however have a small gripe. 1) How can Lego put out an item like this and not include a construction guy with a helmet...... Lol, and 2) why doesn't this unit also include one of those small tools to dismantle the unit . Thanks for the fun times, Lego.Play Experience4.0Building Experience5.0Value for Money4.0Was this helpful?

Incentivised review
This was my very first Lego Technic set and wow this really is a stunning and absolutely gorgeous model, along with an interesting build design. Surprised how big this machine is and the functions all work pretty decent. Took me and my partner over a week to build, couldn’t do it when kids were around so had plenty of breaks.. we enjoyed building this set together it was fun and sometimes challenging but what an experience.! We loved building it together. Good job Lego.! Once built just download the free app to control the bulldozer very simple to use. My friend has the Liebherr model and in comparison Liebherr has 7 motors and 2 hubs, while this only has 4 motors and 1 hub. I think Liebherr has more functions to play around with.. but they both look beautiful and stunning at the end of the day. Overall this bulldozer is a pretty cool set but definitely over priced in my opinion. Highly recommend for the construction vehicle lovers.!Play Experience5.0Building Experience5.0Value for Money3.0Was this helpful?

Incentivised review
Well I was over the moon when I opened this up and it brought back the feeling of being a child playing with my Lego, this doesn't let you down on the high standards of the Lego brand , its very easy to follow especially if your an avid Lego user, there are full instructions to help you construct the Bulldozer and can be controlled by your smart mobile, the tracks are fully adjustable which for me was really exciting and you can also control the ladder blade and ripper via your mobile control+ app. All the parts come numbered in clear bags and you get a full instruction guide to help you construct your bulldozer, this is very big and stands out and well worth the investment. It is very challenging at times but I enjoy this and it is a good project to set aside when you have time. I love seeing the motorised parts that move and bring your Lego to life, I would recommend this for all adults that are looking for to bring back childhood memories or just feel young at heart.Play Experience5.0Building Experience5.0Value for Money5.0Was this helpful?

Average rating5out of 5 stars5.0Excellent kit!
I would recommend this to a friend!
First and upmost no missing parts! Excellent kit! I enjoy building big kits with lots of parts and operating gizmos. This is one of those! Realistic, lots of gears and intricate building sequence's. Took my time to build it and enjoyed every minute of it. Having built the Liebherr 9800 and the Off Road Crane 42082, this adds to my small collection of complex kits. If anything I would change would be the color of the threads: grey would have looked more realistic. The Iphone app is a little bit difficult to use and confusing at times. Overall it was a very satisfying building experience, a great build and can not wait for the next huge kit to come out.Play Experience5.0Building Experience5.0Value for Money5.0Was this helpful?
