As model showcases great otherwise rather mau

with the Arctic tracked vehicle Lego has created a great Vitrinienmodell.
When building the vehicle, I thought at the beginning still Wow that is a new top model, but I had to after completion notice that the implementation of the individual functions is partly very disappointing.
For example, the rotation of the crane structure is carried by the crane to tackle with the hand and turns.
due to the size of the chain links the locomotion of the model is very jerky, and the steering is quite cumbersome.
For the price of 69.99 I would have expected something more than just a great appearance, so the model gets by me only three stars.
