I was first introduced to this product by my PGA teaching professional, Don Powers of Power Golf. The Perfect Release training aid puts you in the groove for your swing. It takes some getting use to, but it is effective. I am looking forward to using it during the off season. I live in Colorado. I recommend you have your own teaching professional work with you using this product to begin with. Contact James Burke, President to order 800-206-7757. This product will be an excellent golf tournament or company client gift.
