We have never had a kid use it in a game. If you fix the grip along with the top hand drill it shouldn't be needed in a game situation. . I think you would have issues at game speed with bat control on selected pitches. I still have kids , while on deck still use it just to get the feel before they go up to bat.
Describe the 'feel' that you want extracted and brought forward into a player's normal swing.
