PlyoBombs: Plyo Balls Weighted Baseball Set for Throwing/Pitching Training (Set)

First off I received my shipment and the 8 oz ball was leaking sand. While I thought this would at first be a problem I reached out to Precision Impact right away and they quickly handled the issue by sending a brand new one. I was very pleased with their customer service and quick service.In regards to use, I am currently using these in line with a professional baseball training program and they are just what I need. I have only used a few times but they are durable and look forward to continued successful use to take care of my arm and increase strength.

These plyo balls were requested specifically by my son, in order to support his baseball training regimen. Although he hasn't yet put them through their paces, he has teammates that gave them a resounding recommendation. He is looking forward to amplifying his training with this set of tools!

Decent ball overall. However, I think the material does puncture relatively easy. I noticed a few punctures already after two or three times of use. If you are looking for batting training, then spend a little more and buy the TCBs instead.

The Precusion impact balls are great. My son uses them in a 4 day rotation and is showing An improved velocity and much less arm fatigue during the spring season startup. I would recommend them to any player!

Bought these for my 16 year old. Increased his velocity by 5 mph in one off season thus far. Make sure you invest in a program to follow as well.

This product was for my son who is a young teenager, he is a pitcher on a baseball team. He is using this for strengthening his arm to improve his pitching. We are very pleased with how quick the item was shipped and the quality of the product

Used them this off season with my teenager to build arm and shoulder strength and prevent injury. He said his arm feels great and is looking forward to the season.

Disappointed that it does not come with instructions on how to use them.
