I got this to make playing ball with the dogs easier.  However, it takes more strength to use this thing than it does for me to just throw the darn ball!  The ball won't come out of the holder thingy unless I stop the Chuckit abruptly, and forcefully at the top of the arc (using much more than arm muscles), and even then the ball goes about 10 feet straight toward the ground.  I use it to pick up the tennis balls before the lawn gets mowed.
