I had a question, I have seen a few things by Sentinel, but while they look good, ANYTHING in pictures can look good. Does anyone have any idea as to their durability? I am unlikely to be bashing things around but I do have to consider that my nephew sometimes is interested in my stuff. He's been fine with things up through MonsterArts, but I know some companies build a lot of joints into their things never seeming to expect them to be used...
