I received the kit for one of these as a Father's Day present.

The parts are very precisely made of laser cut transparent plastic. Each part still has its protective film coating to prevent scratching. I spent almost as much time removing the film as I did assembling the kit.

Interestingly, there are no written instructions supplied with the kit. You must watch the video supplied on their web page. It would be close to impossible to assemble without the video; many parts differ only slightly. Actually the video is a good way to provide instructions. Given that you can pause and single step it it's arguably easier than paper instructions.

All in all a very nice present for a gearhead - assembles nicely and is fun to fiddle with once assembled.
