"The science behind the AceGripz design is valid. AceGripz are designed to increase strength in the batter's swing."
Former Professional Infielder and current coach
"As a 6 year ex professional baseball player, 20+ year high school coach, and 25 year baseball/softball instructor, Acegripz hitting tool has been one of the fastest strength training tools I've ever used. I have a wide range of ages that I work with (8-18 year old boys/girls) and they all use Aceqripz in their daily training regimens. The immediate response from all players is that their grip on the bat feels stronger and bat speed feels faster and smoother."
Former D1 ss at Rice University
"These grips are the best way to hit the ball harder and increase your exit velo. Rice buckets and wrist curls are great, but this is better because it incorporates the most natural thing for a player: swinging the bat. The more you swing with the grips, the stronger you are going to get, it's simple. The best training tool out there, hands down."
