So far so good for my 16 year old softball player. She used it for the first time in a doubleheader this week and went 6 for 8 at the plate. For the other 2 times at bat, one was a line drive at the pitcher who had quick reflexes and the other popped up but overall she had her best hitting of the season between the 2 back-to-back games. I don't know if it gave her confidence, but I am pleased that the first use was so good. I hope the streak continues and this is with her switch hitting left due a shoulder injury when she bats right-handed. Very impressed!
