Before the Swing Path Trainer V4 arrived, my daughter, who is a talented young lady, found herself consistently rolling over during her ab all of the sudden. Despite trying typical drills, she couldn't correct the issue, resulting in weak rollover grounders. However, since using the Swing Path Trainer V4, she has had 25 at-bats with 14 hits, resulting in a batting average of .560 and an on-base percentage of .607. With many games left I have no doubt she will be able to maintain and continue to improve.
I would highly recommend this device to anyone at any age level. One thing I think would be helpful for parents who just don’t know.
Maybe include in the packaging a paper for baseball/softball at what degree should the bat be at contact. Most phones you can go into measurements and you can set the trainer to desire degree you want bat to be at contact. This is what we did and it has worked amazing.
