"I bought the Q-Link on a 90 day trial and that was a year and a half ago. After 60 days my handicap dropped from a 5.2 to 3.8. I found that I was calmer and less frustrated on the course. I have a temper and I find that I don't lose it like I use to on the course. The Q-Link offered a plus that I hadn't counted on. I wear the Q-Link when flying and I am not as frustrated as I used to be in airports."
