The Guardian of the Steam is the third biggest in the series. This one is a perfect contrast to my other futuristic and "realistic" mechs, the designers really tried hard to picture it as driven by steam and I can say they are successful in that. The mech is stable and can pose, the instructions are clear. The only cons are some stickers of the set - some of them surprisingly have purple background while being placed on blue pieces. It's not too noticeable, but a bit annoying. I have to add all WINNER stickers are not of too high quality. They are too thick comparing to usual Lego ones.
