It has taken me years to be able to throw a chuckit, I am a dog trainer and throw a lot of balls. I used the small pro 18 for my yard.  There are several weights of this toy, I can only handle the basic , lightweight model, I am not strong enough in the forearm and hand to handle the bigger version of this ( ultra grip). I bought this to replace the heavy ( utlra grip ) one  I keep on my bike. ( dogs and I bike then throw ball)
