I bought this for my child's practice swings, but they've since graduated from the team, so I'm selling it. Please consider it with an understanding that it is a used item. The grip moves inward during practice swings, helping to master an inside-out swing. The biggest feature is that the grip moves inward. By moving the grip inward, your armpits naturally tighten, allowing you to master a swing with a long impact zone where the head is kept back. Through repetitive practice, you will internalize an inside-out swing and develop correct form.
