"The Batmobile was a great build in such as compact body. Although it's hard to say what the origins of the vehicle and minifigure are from, it's still a cool Lego Model.
Despite the low piece count, the motor / battery box seem to account for the higher price. My plan was to use the motor / battery box for other purposes in the future and this seems to be the only way to get the Bluetooth functionality.
Where it really fails is the controls / handling of the Batmobile. As others mentioned, controlling the Batmobile through the app is a bit of a challenge as well. You essentially have two controls, one to power each side of the vehicle. It moves forward / backwards well, however when it turns it vibrates/jumps a bit. I believe it's due to the grip of the tires and that turning is based on powering just one side of the vehicle (or reversing the opposing side).
For the Bluetooth capabilities this set is pretty cool, however the overall design of the steering for the set detracts from this set being awesome."
