Worn the brace at 2 events so far. I wear the medium & due to my tall stature the tether straps are a bit restrictive. Turning my head side to side is greatly reduced. I will contact them to see if they advise going to the next tether size up. I have no doubt that if ever involved in a high G-load accident the NecksGen REV may prevent serious spinal injury. Absolutely no pressure point pain in the shoulder or neck area as noted w/some other devices Ive somewhat mastered putting the helmet & brace on w/little issue. Just a few more moments involved to ensure my harness straps on engaged into the horns of the brace If you are involved in any high speed track driving, a HAN device is a must IMO
