There are so many major negative points about this set:
• the quality of the bricks is very, very poor.
• All the tile bricks are totally scratched and look very, very bad.
• Many components cannot be fitted without pliers.
• Many production failures.
• One wheel mount is very rough and runs poorly and sluggishly.
• The extension cable was missing.

Hello. In my experience, the DOOSAN parts set is exciting and good. Although some pins and axles don't hold so well, the massive construction of the wheel loader makes it work.
