I have mixed feeling after buying this very new set on special offer. John Lewis delivered as always with a great price and the box arrived in very good condition. I was able to collect from my local store without any trouble.As an avid Lego Technic builder and collector however, I was slightly underwhelmed by this set. There are some new bricks and some novel build techniques, especially the way the suspension works, but on the whole the functionality is just that of a remote control car. It does have a fancy gearbox that would probably do well on the beach in sand but how many people would do that with an expensive Lego kit. The functionality is really not that different than the 42109 Top Gear car.My advice is to wait until prices fall below £200 or keep saving ... MoreI have mixed feeling after buying this very new set on special offer.

It's all about the making of this Lego kit. A couple of hours a day over a week saw it materialise. Climbs an incline effortlessly. Another great Lego build.

Love a Lego technic build and got an excellent discount on this set. Enjoyable build - ok it's a tad slow in RC mode but fun as a bit of variety from the norm.

Looks great, runs great, but it just looks a little bit bland. The model could be improved with a little more added to it (not just adding more stickers!). A great build and fun model. Other reviews are asking a bit too much from a Lego set!
Incredible working model.Really enjoyed building the truck by following the well thought out instructions.Being a mechanical engineer, could appreciate the technical detail when putting the model together.Downloading the control app was easy enough and have used the truck quite a lot.
This was on my wish list but was out of my price range until I saw the price from Zavvi so I ordered it straightaway. Zavvi always pack the item in a strong box with inflated little bags so it arrives in pristine condition. It took just over a week to make spending a couple of hours each day. The result is an amazing 4×4 truck which is great fun with it's 4 motors. There were over 30 stickers to apply which can be fiddly but if you take your time they are fine and finish the model off. A great project.
Birthday present for the husband - absolutely LOVED it. App control works perfectly!! Lots of fun driving it around the garden.
Bought for Christmas gift for husband a really expensive one but hoped he will like it the on very website they have reduced it over sixty pounds again can’t review item as a gift but very unhappy with very appalled at the reduced price before Christmas - not on ! I feel conned
Extremely complicated to build for 11+ children, but after many days was achieved. Great truck when finally working. Price of Technics is always expensive which we know that before buying, but cannot say its value for money. Overall though good quality truck and cool app for controls.
Expensive set but a phenomenal build. Automatic locking differential is a huge step forward. Also the vehicle really shines when displayed. Even when it’s not moving you can tell it means business. It’s an impressive climber and crawler, but all those motors the hub hinder its speed. It is SLOW. Huge potential for modification. I’m looking into switching the wheels for a track set up. I paid full price, and have seen it at a significant discount since. I recommend waiting for that discount before buying
