I tried them out for our last three practice. Kids can hold and throw good with these. A standard baseball is pretty big in size for there hands. We warm up with these at first them change to our practice ball. Be carefull because its small they can over throw the ball with more speed and get someone hurt. Because it small they have to fous more where the ball is coming and help them close there gloves more sense the ball is smaller. Over all its a good training ball. I don't use it for battting just catching only.
