I received my bat jacks yesterday as well. Very prompt Jim, thank you!
I ordered the combo pack(1 hard-1 soft). The difference between the two is very minute. The hard one does seem a little stiffer but not by much. that is not a complaint, just an observation.
I am no hitting expert but if the grip this promotes is the way a bat is really supposed to be held this aid is perfect. We only had time for a few swings but dd said it was really comfortable. Different, but comfortable. We are leaving for vacation today but I am super excited about this.
Thank you, we love the feedback! Good luck the rest of the season
