"First of all this set is not that “technic” compared to some of the “groundbreaking” flag ship sets. One thing I really need to give credit to is the play experience. Honestly Id rather have a set that’s ok interesting to build and works great after built( especially for sets with power functions ) than a set that has a fancy gear box and long drive trains but doesn’t work as smooth as you would expect. This is something that I always had complaints about technic sets. The Arocs is probably the only set that’s satisfying to build as well as to play with. (Highly recommend this set) So in terms of play experience this set really does a great job, everything works really smoothly(thanks to the short drive trains). APP works good as well. The only minor issue with the set is driving. The motors for the tracks is a little bit on the weak side. While on a perfectly flat surface it works great. When on a slightly rougher surface turning is almost impossible as it can no longer handle the torque without triggering the new clutch. A bit disappointed but none the less a fantastic set."
