A wonderful set for hours of fun!
Quick to build, fun toy, LEGO motors for a low price. :)
Nice car, but I was finished with it within two hours, which I found a bit disappointing.
Detailed. The software works well.
Really great!
Very nice set for a very good price, for a controllable LEGO model. Very sturdy and works very well with the app.
