The Part Quality ist very good. Power functions are above Leg* Level.
The build will be finished quick and easy - Instruction is very good and suitable for kids, too.
the focus lies on the driving and this is much better than every other remote controlled (Lego-)vehicle I own. The car is incredible fast and even if you crash into something its very easy to fix it. The remote control is much more intelligent as I expected - it is possible (by following the instructions) to combine both Motors on one direction.
