Well, back in 84 I just got megatron fresh out of the box and after I completing the robot form (who needs instructions?) I said it doesn't look right. The barrel is to be up just like the cartoon....big mistake, whatever you do don't do it :P
That and my Omega Supreme on the first transformation to robot, pulling out the tank treads at little too far can cause breakage
My grandmother and I returned it the next day and the samething happened a week later. I bought one of of ebay last year (mint) and I only transformed it twice, I'm too scared
