Clearer App instructions, instructions that explain how to turn it off, or a button on the app. I had to delete the app, to turn off the motor. I then contacted customer service and they explained two ways that it will turn off
I would recommend this to a friend!

Really should have a remote control
on May 31, 2022
Posted by: Torka
A fine set to build, but having an app instead of a remote control really brings this thing down. I'd never be able to recommend a Lego set that would need to have an extra (non-lego) device to use fully (not counting mindstorm).
No, I would not recommend this to a friend.

Great design, lots of fun!

The Technic tracked vehicle you've been waiting for! Simple, lightweight, elegant design. The 'transformation' mechanism works flawlessly. I like that the controls have a quick turn 180 to make it easy to keep flipping out. Anyone else notice that instructions have you build a section and then repeating it for the other side, the steps are reversed? (even the instructions 'flip') Love it!

Cool Lego set
on March 6, 2022
Posted by: Lindee1017
[This review was collected as part of a promotion.] I received the LEGO - App-Controlled Transformation Vehicle for my he loves it. There were so many pieces to put it together and it took a while to do it but it came out great. The instructions were very clear and easy to read and it made putting it together easy. I was surprised at how durable it is after it was put together. I was afraid 1 little bump into a wall or something, and it would fall apart but it didn't. The only issue I had with it was the app for the controller. My phone isn't compatible, I dont know why because it's a new model Samsung and software is fully up to date, but I was able to connect it to a different phone. My son loves it

Great for quality time!

[This review was collected as part of a promotion.] My son was not to excited about the building part as he was about the playing with it part! He did help build some of it but I did a lot of it. It was still fun though because we got to spend some quality time together while we did it. And after putting it all together my son has had so much fun with it and exploring all of the different things it can do!

Great barebones set with 2 motors and a hub
on August 9, 2022
Posted by: JumpingRooster076
There really should be a pieces nr without the crawler pieces, I guess it's like 50% less than shown. But basically, it's a very small set with big dimensions. And there are many ways to improve the model, so that it won't tip over the moment it touches an obstacle etc, but I find that to be actually not a bug but a feature, it's not a rc toy, it's a lego set, and therefore I think meant to be expanded and to stimulate imagination, and in that regard it delivers great!

Missing one piece so far. Waiting for the missing piece to arrive.
I would recommend this to a friend!

That's no fun. If those wayward pieces aren't just hiding on the floor or stuck in the packaging somewhere, visit LEGO.build/BricksPieces-BV to request what you need!

Lack of info
on April 29, 2023
Posted by: Lilbill
The build went really good ! I had no issues with putting this set together and or working it. But the issue I have is the instruction booklet didn’t tell me how to work the power unit . So there for I had to go to YouTube to figure out how to turn the power on/off on this Lego set . One click to turn the power on and press and hold the button roughly 10ish seconds it will start to flash rapidly for about 5 ish seconds then the light will turn off .
I would recommend this to a friend!
