3x3 Rebounder!
Fantastic product with unlimited uses for all facets of baseball and softball training. Well-made and easy to assemble, we love our rebounder so far!
We have used plenty of rebounders over the years and not one is close to this. It is high quality, easy to put together and operate. My son is the one that put it together. It is easy to take around with you and stores upright. I really can't say enough. I will be getting more for team practices.
Great product! Has instantly become the players most asked for training aid at practice. So much that I need to buy more to ensure all positions can work out at the same time and still be able to do group workouts.
Super easy to put together and great quality. My 8 and 10 year old kids can move and set it up themselves. Highly recommended for anyone looking to pick up a rebounder!
We were tired of the cheap rebounders that never seemed to last more than a few months, and went searching for something more durable. In my opinion, the PRO PORTABLE REBOUNDER 3' X 3 is the best that money can buy. Sure, it is more expensive than others, but you get what you pay for. This thing is sturdy, made of high quality materials, and outperforms any other rebounder we have ever purchased. There are no cons and too many pros to list. 5 stars all day!
Maximum Velocity Sports is a great company and the Queen of the Hill pitching is a great strengthening tool for pitchers. Along with being and excellent audible guide for pitchers to know when they are using the proper mechanics to get most out of each pitch.
I began using this with my catchers a few weeks back. It is a great tool for teaching the catcher to work to the ball with "strong hands." The catcher is assisted by this tool from the beginning of receiving all the way up until the ball is received. One can mix inno-glove drills along with drills using a catcher's mitt. The CRT belt is easy to use and is quite easy to include with the catcher's other tools and equipment. It will fit into the catcher's equipment bag without taking up much room at all. It's a tool that is used at the MLB, NCAA and HS level.
