I absolutely LOVE the Chuckit! I love this shorter one because I throw the ball for my dogs in my backyard and I feel like with this one I throw just the right distance.  With the longer one, I throw farther so I like this one for that reason. Plus, I feel like I have more control over my throws with this length. Regardless of the size you get, these are great because you don't have to pick up the slobbery balls to throw them for your dogs and I can't throw very far with just my hand so my dog gets more exercise when I use the Chuckit! I got this for around $6 as an add on item and it also came with a standard tennis ball style Chuckit! ball.  You CANNOT beat this price in stores ANYWHERE! Amazon for the WIN!
