Four orbital launch successes in four attempts is a legitimately impressive track record in spaceflight. I wonder if this is a technological dead-end though, this rocket can't be reused because it uses only solid-fuel motors. Unless it's really cheap to manufacture I think it'll have a hard time competing with the reusable liquid-fuel rockets being developed in China for commercial use like the Long March 10 family.
