This is robot 17 (铁人17) which I watched its drama series during my primary school. I think only those people who born in the early 70's may know this robot. Bought it from Uncle Ng at CSC yesterday. I cannot expect the toy still got its "value" even Bandai released it in the year 1999. It can transform from robot mode to vehicle mode and vice-versa using double A batteries. Unfortunately, mine cannot be transformed anymore as the toy was not been used for so many years. Two words to say "So Sad".
