Congrats! You won't be disappointed.
To me, the only thing on him that seems to be fragile is the forearm zipper on the side with the interchangeable LED saber arm, as DD mentioned. Other than that, he seems to be pretty sturdy. The belt seems to be a lot sturdier than Vader's fragile belt (probably because it's thicker, for one). Not many parts on him that seem like they can easily break.
Thanks for the heads up! I definitely use the light up arms/sabers on all of mine, so I'll be careful with the zipper.
