Overall this is a good product, but it could use an upgraded means of connecting. During a 14 hour drive, it helped a ton in the beginning but by hour 12 I needed to remove it and couldn't. Wish it had a clip that is easy to remove and put back on. For my size (5'5" 132lb) it feels slightly large, but for lt;5 hour drives, it works great.
