My experience

I have built loads of Lego sets before this but this is my first technics f1 set. And overall it’s an amazing set. The building techniques used and the details are amazing. I’m a massive f1 fan. But I did feel like there was a step missing when it came to adding the front wing from underneath the car. And there was a couple other steps that weren’t as clear as they could be. Other than these tho this set is a must have for any f1 fan

Very realistic

Really fun to build. Very realistic. The steering actually works, and the pistons go up and down when you spin the wheels. My only complaint is the price.

Checks all the boxes

As an F1 fan, and a Lewis Hamilton fan, and a black-Mercedes fan - this set was a must! It predates the official Lego partnership with F1 but it still compares favourably with the Red Bull and Ferrari cars that came out of that partnership. It also compares very favorably against the McLaren Technic F1 car, in that this model is based off of the actual W14E, it has a removable engine cover, and it utilizes the stronger red springs (my McLaren's floor is resting directly on the shelf at this point). Only comment I'll make is that it was difficult to line up some of the built parts during the build, due to there being multiple pins that needed to be engaged simultaneously. Also the connection point for some of these built parts is not always easy to discern from the printed instructions. The digital instructions might make this easier - BUT - I welcomed the challenge and I'm sure you can figure it all out if you just pay close attention and try to make sense of what you're doing. Overall very happy with this set. The McLaren is now at the office and the Merc is on display at home.
