I have the board and I guess you could make one but I prefer to have my feet straddling a plastic board than wood and the board is adjustable for different clubs .
As far as effectiveness I like the board and it does teach you to use the ground . I feel like I have improved my ball striking and I also think my backswing has shortened a little bit but I haven’t lost distance due to the better striking . I think it’s a training aid that I will use often and not one that gets thrown in the garage after a few weeks .
