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.

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!

Not perfect but works
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.

These have red seems (paint)
I will update my review once I use them. Heavier than SmashFactor (by Driveline). They are 2 pieces glued together. That concerns me, as my SmashFactor balls split after about 3 months. Mine have the red seems, as shown in the listing… Made in China

Take these to the cage!!!
We spend $300-$500 on our players bats and if your kid can connect with the ball regularly, you will not only break your bat but also void the warranty in most cases if you’re at a cage. These balls still give you the same look and feel without the trauma to your players bats. I highly recommend this product. This is my 26th season as a baseball coach and I’ve seen plenty of bat breakage.
