Purchased this product at the recommendation of my golf teacher. Have golfed for 30 years now, about an 11 handicapper. Have a strong tendancy to be a little too right handed so I would usually be left of my target. This really showed me that you don't need to break your wrists at impact as many previously had taught me. Takes a little getting used to at the range. Be sure to do as the video indicates, hit 20 with it on, 20 without it. I keep this in my bag so when I'm at the range and on the course, I can put it on for a bit to get the feel. 5 stars
