Recently I dug mine out to fiddle w/ on a Saturday and the clear energon arm broke at the bicep as I transformed it from jet to robot. I thought this was worth noting and warning on the boards as we have two repaints of this toy in this years botcon set. I bought another on ebay and as far as I know I transformed it correctly the first time because the new one did not break. Just hope you guys are extra careful especially w/ that swivel hinge on the arms below the shoulder. Never was comfortable w/ that transformation.
