Review on Jingwei Swing Plane Corrector and Posture Indicator - Golf Swing Training Aid by Larry Sabey

Great idea, good price, sorry for the poor quality. Simple concept, place a laser at the end of the stick to identify your swing plane, but I found: - The basic structural design is very good, especially the stick mount - The problem is the switch, it's weak and I'll install it, If you mess around with it you will get a bright light but after a few seconds your laser will dim and then turn off. Will try again when quality/design issues are resolved.
