Query: Golf swing aid

This is quite a bit of money to pay for a piece of plastic, but well worth it. I find it indispensible as I work through the process of improving my swing. I needed a lot of work to relearn years of bad habits. This simple easy to use tool has proven to be highly effective. I am a 25 plus handicap golfer. This may take 10-15 stokes off my game based on how I am now stroking the ball. My cousin who is a sratch golfer found the Swingyde useful to help him with finetuning.
