なぜかバッティング練習をすると後ろの手（右バッターなら右手）の親指の付け根が痛くなっていたのですが、これをつけてから痛みが出る事がなくなったのと、後ろの手のグリップがしやすくなって自然に押し出せるようになりました。

竹バットでの練習で手を神経を損傷した経験から購入。保護に加え、余計な力も入らなくなり、今では必需品となっています。

30 days late, product as advertised but never arrived as indicated.

Looks like a silly rubber ring when you first get it out of the packaging but don’t be fooled. It helped my batting grip and it certainly helped my top hand turnover. I developed some bad habits after an injury and then trying too hard to get back to my regular. The pro hitter helped me break out of a slump (went 3/3 and 2/3 the first two games with it) and I don’t see myself putting it away until the end of the season.*edit: turns out I did keep the thing in my bag but after my third game with it I felt confident enough to go without. I’ve been hitting well ever since. It might seem more mental than physical but I was gripping the bat all wrong after an injury and this helped be get back on track and I noticed that my grip did change (for the better) after having used the pro hitter.

This little thing is fantastic. My son always had stinging in his hand when he hit the ball and he was afraid to hit. However, once we put this over his thumb, it lessened the sting tremendously. He has no issues taking a good swing now thanks to the ProHitter thumb guard.Make sure that you get the right size because some videos say that you should order a size smaller than what you actually are. For my son, we ordered youth size and it fit fine. He's also wearing gloves, so that likely makes a difference too.I highly recommend the ProHitter!
