I was actually surprised at the quality plastic and heft on this Megatron. If any joints are loose all have to do is tighten (carefully) the screw to the joint, will minimize the looseness of joint. Was impressed on the ease of transformation and resemblance to the movie. I am a stickler for movie accuracy. One thing I did notice is the face sculpt looks a bit like the creeper on Jeepers Creepers movie. Also the rear skirt piece should of been included or intergrated into design some how. Over all very impressed and satisfied with this purchase. For a K.O. it is one of the best at this price point.
