Premium Foam Balls

This is a very low end version of what I believe you were selling as a knock off MARV ball for the half bat, or potentially the aero-swing? Either way, I cannot use these. You should coduct more testing before standing behind a ball of this caliber on your website. These will end up being $50.00 chew toys for my dogs. Just being honest... Take care,

These are a great training tool

Balls really help with my swing. Use them pretty much any type of surface and not issues. Great product!!!!!
