- March 24th, 2021Average rating5out of 5 stars5.0Great features and priceI would recommend this to a friend!Purchased for: SelfVery classy build with great detailing and awesome working mechanics. A very striking model which proves Lego can produce a great product at a good price point. There was no let down on part count, how it went together and functioned. I know they had a valid reason but I rather wish the windscreen was clear rather than frosted. Highly recommend this kit.Play Experience5.0Level of Difficulty3.0Value for Money5.0Building Experience: Expert LEGO builderWas this helpful?55Heavy-Duty Excavator
