Not this one though, this one needed to be built and I'm glad i did! It took me about 1 1/2 hours to build, but I found the whole process simple and easy to follow. Its surprisingly study as well and has survived many fights with my twins girls who are both fascinated with lego now....no that i can let them build anything yet (they are 2 years old!) For the money, its well worth it! Review: Looks good - It's Lego, so it goes without saying that it's a quality product. Good fitting pieces ( none mssing) and excellent instructions. I don't know if it's me, but for £60 it didn't take that long to complete. Good looking, working model non the less. ## Features - Heavy-Duty Excavator - The toy set lets kids see how construction vehicles really work with moving shovel and arm, plus running belts, just like on a real excavator - There are 4 cones to manage the building site, plus extra LEGO pieces to use as bricks for scooping up during all possible excavation works - Manufacturer recommended age: 8+ - Number of pieces: 569 ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B08G4CKL16 | | Age Range Description | 8 year + | | Best Sellers Rank | 175,270 in Toys & Games ( See Top 100 in Toys & Games ) 4,779 in Toy Building Sets | | Brand Name | LEGO | | Colour | Multicolor | | Customer Package Type | FFP | | Customer Reviews | 4.7 4.7 out of 5 stars (5,694) | | Educational Objective | Creative Thinking, Dexterity | | Global Trade Identification Number | 05702016890976 | | Included Components | LEGO Technic Heavy-Duty Excavator Building Set 42121 | | Is Assembly Required | Yes | | Item Dimensions | 28.2 x 26.2 x 7.6 centimetres | | Item Type Name | Building set | | Item Weight | 640 Grams | | Manufacturer | LEGO | | Manufacturer Part Number | 42121 | | Manufacturer Warranty Description | If your new LEGO set is missing parts or has faulty parts, LEGO System A/S will replace these parts free of charge through our Bricks & Pieces service.

Movement occurs by turning what is referred to as the hand of God black wheel. This black gear/wheel when manually turned causes the bucket to move, also lifts/lowers the arm holding the bucket. I hope I have satisfactorily answered your question. **Q: Would this be suitable for my son's 40th birthday? He is a Groundworks estimator.** A: Sorry not sure. I bought it for my grandson who is 8 and he did it in one day. He has loads though so he loves doing them. My daughter said he loved it. I'm sure if he likes Lego stuff he will enjoy doing it. Your never too old. **Q: As a prime customer when will I receive this item if I decide to order** A: When looking/examining the item on Amazon, this is done by entering the Lego set number, Amazon will advise when delivery will be made. I hope this answers your question. ## Customer Reviews ### ⭐⭐⭐⭐⭐ A very study and entertaining model! *by M***N on 22 September 2022* I'e always loved Lego Technic and have recently started to buy models as future investments.

Good fitting pieces ( none mssing) and excellent instructions. I don't know if it's me, but for £60 it didn't take that long to complete. Good looking, working model non the less. ### ⭐⭐⭐⭐⭐ Good investment, money well spent. Lovely set. *by P***E on 21 July 2021* A lovely, satisfying set to build. Bags are numbered from 1-4. Instructions are easy to follow. Each numbered bag covers a section in the instructions. Building the 86 link drive chain(43 links per side.) requires concentration and discipline.
