His left arm is a little loose. He had difficulty holding it straight out extended which was disappointing. The head sculpt is a pain to get on. At first I thought the ball joint was too small. Pulling off the head requires a bit of force and the shoulder pauldron usually pops off with it. Hand and feet came off and on without the need for force. Basically your typical sideshow trooper. I've gotten lucky so far and all of mine are able to hold the poses I want. Rex is probably the loosest one I have.
He looks great though. Easily the best trooper I have. Can't wait for Arc Echo and Fives now. Those will be the last for my clones collection.
