Excellent product, but keep it away from chewers.
Style: 2.5" Ball
This is a very strong and effective launcher and could have lasted a very long time had my 9 month old not chewed the ball claw end off. I will buy again.

Our Dog Loves This Ball Thrower So Much
Style: 2.5" Ball
Works excellent for dogs that like to fetch! Our family dog loves this toy. He will bark and jump as soon as he sees us pick it up. The dog next door to us gets excited when he sees us play with our dog with this dog ball thrower. Its that good for dogs who love to fetch and run. Perfect for the young and elderly to play fetch with a pet dog. If you have back or shoulder problems works very well. You don't have to bend down and pick up a slobbery ball. Nope you use this to pick up, grip up and grab the ball. Wish every dog could have this ball thrower in their lives. It has changed the way we play fetch with our dog.

Good Pet Ball Launcher
Style: 2.5" Ball
I bought to throw balls for my Aussie. He does not like to tennis ball that came with it and chewed it up in less than one play time. The launcher seems to be of good quality and works well. We bought different balls made for launchers that work well.

Must-Have for Dog Owners (Whow have dogs that like to fetch)
Style: 2.5" Ball
Soon as this launcher arrived I went outside with the dogs to try it out. Long story short: This is a great fetch toy. I am able to launch the ball pretty far with little to no effort, and picking the ball back up is as easy as grabbing it with my own hand. The toy itself is very sturdy, so much so this is the only fetch-toy I'll ever have to buy. Considering how durable it is, I don't think I'll ever need to buy a replacement. I believe Chuck-It is the most popular option, and because this is the first fetch-toy I purchased, I can't really compare it to anything else. A few outlier reviews said the ball was difficult to launch, and I have to disagree. It has been so easy to use I can't possibly see what the problem is. And no, upper body strength is not a factor as I virtually have none. People can get great distance (Half the length of a football field by my eye) in one simple, easy motion. And if other products can launch the ball farther, so what? How far is far enough? Is your dog going to throw a fit because it went 40 meters instead of 50? No. They will not. For anyone upset this toy doesn't launch far enough, ask yourself this: Is the toy for their dog? Or the human who bought it? The bottom line is this: It feels like it's built to last, it's inexpensive, and it does what it is supposed to do. So long as a toy is "good enough" I don't see the point in splitting hairs and trying to determine which fetch toy is the absolute best. Saying it's good enough is a bit misleading though. I can't imagine how a dog toy like this could be any better. It's a must-have for any dog owner. Unfortunately, only one of my pups likes to fetch...

Works Like a Charm!
Style: 2.5" Ball
WoW!! This thing is pretty cool! It can pick the ball up off the ground - and with little effort - It can throw the ball 3X Higher and Further than I ever could! It wont hurt my elbow or wrist ( way better than before when I was wearing myself out ) I don’t know how I ever got along without it!! It's a must have if your dog loves playing ball. :-) Update: I've had this For 7 Months Now- it looks and works Great just like the day I bought it- Thumbs up!
