  1. Great Bat
    The bat looks, feels and performs great. It is solidly built and is impressive from the detailing on the barrel to the supple leather grip. My son has noticed much less vibration and "stinging" from mishits as compared to other brands. He brought it to his little league game last night for the first time and pretty soon half the team was using it. it also has a unique sound on contact similar to the "crack" of a wood bat. I definitely recommend this bat for your player.

  2. My kiddo immediately noticed the difference in pop
    Folks, the demo program is legit. No other bat company, that I know of, does this. You have nothing to lose, and no worries about buyers remorse.

    We got 2 different size bats to try for two weeks. My boy utilized them during indoor league and practices for the demo period. My kiddo immediately noticed the difference in pop when compared to his Louisville bat. The ball certainly looked as if it jumped off the bat when compared to others.

    Ultimately, we decided to go with True for his last Little League season. We plan on doing a demo for the USSSA for the tournament season.

  3. True is legit, and the demo program proves it
    We have an active little leaguer who loves to play the game, we noticed True Diamond’s demo program which helps ease the tension of purchasing an expensive bat. Boom! Bat arrived in 72 hours and he was swinging in both games and practice. We even tried a second model to confirm the best fit. True worked with us through the entire process. Now we are going to be swinging a T-1 and we couldn’t be happier.

    True is legit, and the demo program proves it. Happy hitting and good luck.
