Just as good as an actual Chuck-It
Color: Blue Dog Ball Launcher with Squeaking Handle, Size: One-Size
This is much cheaper than a Chuck It. And it’s just as good. My dog loves it.

Game changer
Color: Blue Dog Ball Launcher, Size: One-Size
This has been such a game changer in playing fetch with my dogs. The ball fits inside great and it throws smoothly and goes quite a distance.

Learning curve - but super fun
Color: Blue Dog Ball Launcher with Squeaking Handle, Size: One-Size
Okay- don’t get me wrong I know how to use a chuck it. But the handle of this has a squeaker - which is fantastic to get my ADHD dog to focus! Buuttt beware- it will take off your fingernail if you aren’t holding it properly when throwing. I learned that the hard way. Twice.

BUY IT!!
Color: Blue Dog Ball Launcher, Size: One-Size
Great product!! Releases the ball nicely and saves my arm from dying at the end of the day. The construction of it feels flimsy but for someone who uses it AT LEAST 3 hours EVERYDAY, I would say it's pretty good quality. Would highly recommend!!

Dog hasn’t destroyed the ball yet!
The ball that comes with this is amazing. I have a 1 yr pitty that destroys everything! But this ball she has not been able to rip apart. I bought extra balls I was so impressed. She loves it too, takes it to bed with her.lol
