For the most part I enjoyed it but the end of the video sucks. It includes people at the Michigan lab cutting into the Vaporflys. At the end, Geoffrey Burns has an OT qualifier run a mile in the Vaporfly and another mile in the adidas Adizero. But then it just ends with no analysis of the mile run other than the guy saying the Vaporflys felt amazing. I thought they'd analyze like speed or heart rate or something.
