I was an owner of the original Max Factory Kasumi and while that was a beautiful figure, she leaned quite badly. I haven't opened this one yet as I can't find any reviews on her stability. Although leaning is far less frequent with Japanese figures, it still does happen and I will exercise caution with Kasumi.

In terms of the improvements, Max Factory did an amazing job. The refined version definitely blows the original out of the water. I'd love it if they refined Kasumi in her original blue costume as well.
