Not a long shot
Style: Sport, Size: 12in
This item is much smaller than I thought it would be .
The ball is full sized . But the thrower is very small.
Works okay. But does not throw the ball very far . It’s okay for me . My dogs are small. My yard is too .
But , this is not going to throw balls really far . Like the long ones do

I would buy this twice!
Style: Sport, Size: 12in
This Chuckit! Dog Ball Launcher 12M Sport is the perfect product for the dog park! It makes games of fetch so much easier and more fun — the long handle gives great reach, so I can launch balls super far without even bending over, and our dog goes absolutely wild chasing them.
It’s comfortable to hold, works smoothly with 2.5" dog balls, and really saves your arm and back if you’re doing a lot of throwing. The design is sturdy and reliable, so we can play for longer without worrying about it snapping or wearing out.
If you spend time at the dog park or love playing fetch, this launcher turns a regular game into something even better — our pup gets twice the exercise and we get to enjoy every minute of playtime!

Caution can cause addiction
Style: Sport, Size: 12in
My dog has become addicted to tennis balls because of this! She sees the blue handle and she immediately loses her mind! I love it because I don't have to bend down as far to pick up the ball, which is amazing after 2 back surgeries.

12 " too short, no direction.
Style: Sport, Size: 12in
I got the twelve inch handle. It is too short and does not flex enough to release ball in right direction. Its almost impossible to aim and doesn't sent the ball far enough.
