I purchased this when I purchased the medium max glow ball.  I love it because not only does it enhance my wimpy throwing, but it saves my gloves when I'm playing with my dog in our super muddy backyard.  I wouldn't purchase it for a super small space because I have to be careful not to throw it over our fence.  The ball really does go a long way when you use this. I definitely recommend using it if you have enough room.
