I couldn't resist and ordered one. Oh MY God was I disappointed....
He is so hollow, thin and cheap. It's an embarrassment to the Grimlock name...
I do find the robot mode fun and very pose-able, but his floating shoulders and shin guards that don't lock in well really annoy me. He is very light, but at least that makes it easy for him to hold a pose. Don't look at him from the back.
The dino mode is awful. Hollow from the bottom, if you connect the legs in he has not movement at the hips. A stomping dino that can't stomp! I think the head is a bit small as well. I find the clever use of the light gimmick (i.e being small and contained within dino neck) has not been capitalised on for the robot mode and the tail is just waaaaay too fat.
Very Shoddy, Very poor, very cheap feeling toy.
I am severely disappointed.:(
