Waist is just one of the things... It's not as flexible as 1/100
Exia, as in not alot of range of motion... Some joints are stiffer
than it should be, but still wont hold 0 raiser's weight (the
shoulder GN drive mount), other parts are just too loose (the
shields comes to mind)... And the head can't look up, not even 10
degrees... Oh not to mention the upper body likes to detach itself
if you move it too much, like when installing 0 raiser....
The only saving grace it had, imho, is the GN drive lights
and the fact that it's a 1/100 OO raiser... and the CB stand,
unless bandai starts selling them...... and if they start selling
1/100 seven sword add-on for 1/100 gundam 00
