Review on Jingwei Swing Plane Corrector and Posture Indicator - Golf Swing Training Aid by Ricardo Mercado

I didn't want to buy it after reading negative reviews, even at a low price. My response to negative reviews is you are doing it wrong. This is an extremely effective tool for leveling the swing, especially the swing. But you have to use it right - use it indoors or in your garage, off the ball. This is a red laser, difficult to see outdoors. And the power button is a little touchy - if I accidentally hit the floor and shake inside, it will turn off. So don't even think about hitting the ball. This is very handy when you use it indoors and keep rocking back and forth without hitting the ground or the ball. My swing was too shallow. I only spent a few minutes rocking back and forth to make sure the butt of the racquet was pointing where the ball would be on my backswing. Immediate and valuable feedback that really helps swing the plane. Screwing this all the way into the racquet's grip seems to me to line up perfectly. I can't imagine a better swing training device for the price.
