Review: Pleasantly surprised with the realistic performance of the product. - Great product. Balls are durable and have a true flight off the machine to the batter. We used them on a HackAttack pitching machine with the machine set as high as 85mph and the ball flight remained very consistent. Balls have been used daily for the better part of two weeks and we haven’t noticed a change in performance of the product. Balls also give you different looks when placed into the machine in a four seem two seem configuration. When squared up the balls deliver a true flight off the bat. Product really helps a batter get plenty of reps without the potential bat damage and the occasional sting from contact. Must have for any player that works with a pitching machine.
Review: Best pitching machine balls out there - - even denser and better than the SmashFactor balls. - Even better than SmashFactor balls! These work great in pitching machines like the HackAttack - - feel and respond the same as hitting a normal baseball - - without damaging your bat or the need for a cage bat. Not to mention - no sting on the mishits or worry if the pitching machine decides to randomly throw one high and tight. Wish I would have had these over the past few years. My son can use his in-game bat as much as he wants in the cage which has been awesome!

## Features

- Realistic Feel & Flight: 3.5 oz dense polyurethane foam design mimics the diameter, weight feel, and flight path of a real baseball for game-like training.
- Instant Contact Feedback: Requires precise barrel contact to achieve high exit velocities, revealing mishits with immediate spin or misdirection off the bat.
- Safe & Sting-Free Swings: Softer foam absorbs impact to prevent hand sting or broken bats, encouraging full-intent swings during high-velo training.
- Durable for Heavy Use: Engineered to survive thousands of machine reps, making them ideal for daily cage work, hitting labs, and elite training environments.
- Train Like Real Pitchers: Seam design allows hitters to see true ball movement — use a 4-seam orientation for backspin and carry (ride) or a 2-seam orientation for arm-side run and sink, just like facing live pitchers.

### ⭐⭐⭐⭐ Not perfect but works
*by B***N on December 9, 2025*

Other than the price. These are really good balls to feed a junior hack attack pitching machine. Adds about 5-10mph and allows for more reps since the kids don’t get tired as soon as with normal balls. Some kids complain that the ball doesn’t drop like a normal ball but it is great for hand eye coordination. Also the red ink quickly goes away off the ball. Not a big deal but you are left with just a white ball.
