That looks exactly like the one I purchased form PChome right when they came out. I ended up selling the asian-printed keycaps to someone. I still use it sometimes. It works normally, ofcourse. It's that exact model number and everything.
My left alt no longer works. This was an issue with some of them, and I hear newer ones are good.
Totalchaos: I strongly disagree that "everyone should" use US international as their keymap. I have on use for the added characters/complexity, and using QWERTY is just silly when I already know Dvorak
