    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...

    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!

    Better Design - Better Materials - No Sticking
    Style: 2.5" Ball
    Been using Chuck-It launchers and plastic balls for a very long time and they were always a little sticky on giving up the ball. This makes it tricky to throw grounders with precision and can overshoot the fence in the backyard. A couple of years ago, Chuck-It changed the material to a stiffer plastic that made this problem more pronounced. I even tried custom sanding the cup to get just the right grip. The Fetch-It launcher (using the Chuck-It plastic balls) uses a three-pronged claw with soft rubbery ends that releases perfect every time. The material costs on this new one are noticeably higher while maintaining a somewhat lower price than the brand name original.

    Meh
    Style: 2.5" Ball
    It "works" but it isn't very good. The grip is so loose on the ball, it lets go early and doesn't thrown very far. A Chuckit is so much better, I can get 3x the distance with a 25" Chuckit. This thing is kind of a waste.
