Well worth the money i was fitted with Henry Griffitts two years ago and am wrapped at the feedback i get from them. I have noticed significant improvement in consistency. By that i mean if i have a swing problem i get the same result all the time instead of one shot going left and the next going right. At the time it cost me $50(AUD) to be fitted which was taken off the price if you purchased a set and you if not satisfied after three months they will refit you for free. Apparently this happens very rarely and it did not happen to me.
