I used the system for 3 months in the spring of 2019 every other day but due to injury in upper back in spring of 2020; did not even swing them once before the season started. Albeit I was a year older this year, I found my average drives were down ~15 yards in 2020. As soon as January rolls around and feet are recovered, I will be back on them and anxious to get some distance back. The system really does work.
