hahahaha, I really had to laugh when seeing this product. guess this is cool for kids, and those who like this kind of things. programmable, so also something to learn and changeable. it is quite expensive though, more than 300 us dollars, while the finishing of the prototype is quite rough (3rd printed on low quality printer). i do hope the finished product has a better look and feel of the helmet itself (using better, more fine grained 3d printer, or other production technique).
