After completing the product we wanted to drive it, but it turns out the vehicle is too heavy for the engine. The motor and controls works, but it doesn't have enough torque to move the car. We also tried replacing all batteries with brand new Duracell batteries.
My son got super disappointed... 😢
No, I would not recommend this to a friend.

Hmm, something doesn't sound right! A bit of rebuilding might be in order, while making sure that each part is in the exact position shown in the instructions. It's also super important that the gears have extra room to turn. If that doesn't get it moving, reach out at LEGO.build/Service-BV so we can help!
This is a very advanced in unique product. I'm not aware of any other motorized Lego that could be controlled for the app on your phone. Building is not for the beginner or even the average Lego enthusiast. This is a difficult vehicle to build and you really need to use your three-dimensional skills and study The diagrams and pictures to build it correctly. I had one of the front wheel hubs on upside down as I didn't realize from the picture that they could be oriented with the two tabs towards the top or towards the bottom in the car was sitting on an angle, and the suspension was not working symmetrically. It took quite a while, but I finally figured it out, I have not finished the product and tried it with the app so I really can't comment on how much fun it'll be to drive and how much control you'll actually have over speed and turning in maneuvering.
Sticker intensive? Yes. That being said, Lego stickers are of such high quality, they’re very forgiving. It’s worth the effort. Be careful in one of the final steps when inserting four grey pegs through the bottom. I didn’t realize they were meant to capture the entire side assemblies, and they are hard to get out once they’re in. The build was fun, the car is very solid, and it’s a bit more zippy than what I’m used to with technic. Overall highly recommend for something to do between bigger sets!
The car is really nice but it will be better if instead of batteries it can be recharged. It runs out of batteries really quick and it needs a lot. Same thing happened with the trains that I also bought. Also, It will be nice if it can open the doors. Thank you
