Review on Jingwei Swing Plane Corrector and Posture Indicator - Golf Swing Training Aid by Joe Jordan

The product worked as expected for 2-3 weeks but started shutting down almost every time it was turned on. I was happy with it before, but now the slightest vibration or shock and it turns off. Even just lightly touch the side with your finger and it will turn off. I told the seller I'm waiting for an answer. Maybe an anomaly, maybe not. Anyway, this product didn't last at all. I have never dropped, knocked or mishandled it. I just screwed it onto the end of the stick handle and started practicing indoors.
