Not sure if it was just mine or could be a widespread defect, but the arm on my Brisko (Fangry headmaster) from the 4 pack broke off during transformation. This was transforming Fangry from beast to robot, not Brisko (sans moving the legs). Just be warned that the ball joint may be brittle. I am not sure if I am going to trade it out or just use the titan master. If my target has a few I will probably swap.
