I got the h-1 because even with my nvg's i will never mount them on my rifle, for me the IR laser is the better tool for that job. I think most people buy the t-1 because it is the cool thing to have, and they honestly think they will mount NV on their rifle at some point in time. As far as the t-1 being more durable, maybe, but if you break either one it is probably because you dropped if off a mountain or stepped on a IED; they are both bulletproof. I think it is a personal decision, but my NV stays on my head, so the h-1 is fine for me.
