I would like to tell you about my use of my GO. I had a stroke a few months ago and hadn't used my GO since, until about 4 weeks ago, when I was helped getting it on my head. and within minutes I found I had better movement in my arms and my wife said my face looked happy. it was almost like id never had the stroke. until I stopped using it. There is hope I will recover fully. . So I would like to thank you guys, and I look forward to the Quest .
