"I would rather describe it as an artwork. Really impressive by the curve outside and the gears and engine inside. But something need to be mentioned is that the PDK gearbox sequence is wrong. Also, the double engagement of PDK occurs frequently which can totally stop the gears from functioning. It's a disappointing flaw. If you want to own this model and have a better functional chasis, you may need to search for some fan-made improvement (e.g., on Eurobricks forum). Thankfully we have talented designer in LEGO group AND talented fans all over the world. Together we may see more extrodinary models."
"Firstly I am disappointed that there is no option 'China' in Country and you still force me to choose one…… Well I have to admit it's a really cool model with great playability and can be a fantastic ornament on your desk. You can put it in unlimited possible poses. The scale is also very nice, make it a tall and strong Vader in front of you. But the joints are not that flexible, preventing from some poses like driving the BMW R1200 GS (42063) (refer to the picture). Also I hope LEGO group can produce left and right hands respectively with a clear thumb putting on other fingures like real fists of human, cuz it's a little bit wired to see both hands using exactly the same part which the thumb is put on the middle of the fist."
