The R-Jarja is a fine HG build, but I've enjoyed other builds more. I think it is supposed to snap together like normal, but several pieces (especially the front of the head) would not stay on on their own and required glue. Even for an HG kit, I felt like there were more pieces in need of painting than usual, especially the yellow on the legs. Overall it's not a bad kit, but not worth going out of your way for unless you really like the design.
