"As a huge Technic fan, I am very pleased with this model. I had to get my hands on the new Control+ system as soon as possible and am pleasantly surprised. New planetary hubs and stronger, longer CV joint components are going to be game-changers. Modular design means the body is easily removable. Don't be concerned with the price to parts ratio. The Control+ is very robust and adds quite a bit to the play. There are achievements and badges to earn inside the app, which makes it pretty hard to put down. As much as I love the older 9398 4X4 Crawler, I was concerned this model might have some of its shortcomings. I was surprised by the increased speed of this model over the 9398 while maintaining enough torque to handle most of the obstacles I threw at it. If you are a Technic fan, I don't think you'll be disappointed."
