Review on Jingwei Swing Plane Corrector and Posture Indicator - Golf Swing Training Aid by Dennis Goozmer

After using this laser for a few days I really feel that this device has helped me a lot with my rotary plane to enhance. I mostly rocked with a short, heavy exercise stick. After just a few days and about 30 minutes of using the device, I went to play golf and started hitting the ball much more accurately. Great tool at a great price. The problem with the device is that it shuts down when I try to swing hard with regular racquets. I swing my driver at about 100 mph and if I swing at more than 60% power the laser turns off mid swing. It looks like the derailleur needs a heavier spring to handle the centrifugal force of a mid-paced turn. Just an annoyance. I hope that the manufacturer will fix this problem. However, the device still costs $16 and I was able to get a lot of value from it in a short amount of time. I have not seen any other device that could bring such great benefit in a short period of time at such a low price.
