Yup, very good indoor device or out door, the balls are heavy enough that a little wind doesnt faze them. I dont remember the speed - its good enough. Definitely a keeper.
it is very good especially with some sort of hit stick. The down side is hard to tell when ball is being thrown towards the batter. After a while they can time it out pretty well.
i have students from the age of 8 all the to age 54 both girls and boys it works will with all of them. They like the feel of hitting the small jugs ball better than hitting whiffle balls because they can feel the ball come off the bat.
