Fun play, quick but tricky build

I purchased for sons Birthday. He is 6 and builds a number of sets above recommended age. This comes in four bags and like other technic builds parts of assembly process can be challenging. This is not impossible but you do need to pay attention to instructions. The overall build doesn’t take long as the appeal of this set is the play once assembled. Once built the play is fantastic. It is fun to drive and is VERY sturdy. You can run into, over, and climb walls and not worry about it coming apart. The motor and battery pack is easy to access after assembly and doesn’t require you to take apart to change batteries. This is a fun set and a good beginner remote control vehicle. You do need the app on your phone or tablet to control but it is easy to use.

Awesome

Very pleased with this build, especially at the price the app control function is better than i expected. Keep in mind that its not the fastest RC style car but the tracks make it a very nice and practical indoor RC car that can climb over obstacles well. The app even comes with built-in games where you can use the car to drive through virtual gates or collect power cells. My son was also very excited to share with everyone the inner workings of the car with the included motors and battery pack. Overall this is a great buy and would highly recomend to anyone that loves Technics and RC cars

Battery contacts were not working

My husband had to put thin foil in order for the battery contacts to work, we definitely expected for this to work how it was supposed to

Lack of info

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 .

Good, fun product, tracks come off sometimes

This is my son’s review. It was easy to build. Good instructions. Easy to link with tablet but sometimes the hub didn’t process. Log out and then log in and it works. The tracks come off when you drop it from a certain height or you don’t put the tracks on tightly. I enjoyed playing with it watching it flip orange and blue and showed my family. I played with it a lot at first but not as much anymore. It would be better if I could add accessories like snowplows and blasters. It would be cool to put in a guy who would fit. all in all, a good toy.

A set that you can build and play with for hours

This set is awesome!! I love the fact that I was just able to build a working remote controlled car. The sticker sheet was probably the only thing I didn’t really like doing. The app is amazing too. It can tell when you flip and on what side you are on because it changes the color of controls to go with the color of the car. I had a lot of fun running it around the house. I only wish it went a little faster but I still love. 10 out of 10!! Recommend!!

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!
