Got my BT Grimlock. It feels solid, but i think it has considerably lesser die-cast than the rest. I found a bad patch/chip of paint on the side of the bonnet which can't be seen when you close it. But in robot mode it kinda sticks out a little, so u can see it up close.
The joints on this thing feel kinda loose. The ball joints on the elbows came off when i was transforming it. The door joints keep coming off as well which was abit annoying. The gun handle peg doesn't quite fit tightly into the left arm. And what annoys me the most is the thigh ball joints are pretty loose, so Grimlock will do "splits" under its heavy top if not posed properly.
But overall, this toy rocks! Looks big and bad, like grimlock!
