This was my first technic set, and it didn't disappoint. The amount of detail and the techniques used are simply amazing. Looking forward to my next technic set.

Excellent Gift for a petrol head

My daughter is a real petrol head. She loves everything racing, from Formula One to e-cars. She knows the drivers, the cars, the tracks, you name it. She is studying to be a physiotherapist and is in her third year, but has been battling with extreme pain from a back injury. She just had a successful surgery to remove scar tissue and part of a bulging disc that was putting pressure on nerves for her legs and lower body. Before she went in for the surgery, we were anxious about the outcome and whether she would walk again, and I bought her this kit as a motivator. She was so happy and the day after her discharge from hospital, she started the build. She follows instructions meticulously and managed to complete the build in two days while lying in bed convalescing. The instructions were clear and intuitive to follow and she thoroughly enjoyed the experience. Happily she is walking around now, relatively pain free, although she still has a long road of rehabilitation ahead. She will be building more of these in the future, I'm sure. Thank you.

This was a highly fun build from start to finish. I love how you start with the inside and mechanical parts, creating and building the pistons, watching them move up and down. It feels like you are building a real car when you build this set. In fact, any Lego Technic set for that matter. What I enjoyed about this set is, is the size of the model, I love a nice big build as well. It is a beautiful display piece. It fits well into my Technic collection. Applying the stickers was also joyous because yet again, it feels like you are applying vinyl onto a vehicle, creating that feeling that you are building and constructing a real car. The colors are great and bold, and the car really stands out with its metallic sheen stickers. Then comes my favorite part, apart from building, I love photographing my sets/builds/cars and this one was such a joy to photograph. I highly recommend this set, purely based on how fun it is to build, and how realistic this model looks once completed
