This training device helps the average golfer find the proper slot on the downswing. It serves to keep arms/elbows connected and prevent the trailing elbow from “flying,” causing inconsistencies with results. Without help, it was a bit tricky to fit this device to both arms, but once I got it on properly, it really did help me contact the ball more squarely and solidly. It encourages a shorter backswing and a slower swing overall, which gives you a better chance of striking the sweet spot more often. I used it to help cure a shank that had crept into my swing, which it did do. I liked the solid feel I was able to attain wearing this device, but it felt cumbersome at times as I worked through a bucket at the range. And, of course, this can only be used at the range.
There’s also a spring built into it, which I still can’t figure how to employ. The instructional video calls for squeezing your elbows together at impact, compressing the spring mechanism. It works with considerable effort, but it’s confusing and I avoided attempting this squeezing action after a few tries. The instructions say it’s not really that necessary to engage this spring to benefit from the device, but it seems to be key to obtain full benefit. As a result, my use of the device decreased over time.
I generally don’t have difficulty finding the ideal slot on the downswing so I wasn’t too concerned about its full benefit. It did help cure the shanks which I’m very grateful for. It helped keep my arms closer to my body throughout the swing.
Would I recommend purchase? If you’re a beginner who slices a lot and is very inconsistent with your results, yes, I would. But if you weren’t shanking and are a low to mid handicap player, I wouldn’t bother with it
