Superior quality
Style: Classic, Size: 26in
We have 2 Australian Shepherds that never get tired. The launcher is able to trow the ball very far and very durable. Dogs love the ball and they were not able to destroy it yet. We are very happy with our purchase.

Fetch? Yes please!
Style: Classic, Size: 26in
Great for fetch. Small learning curve to release the ball where you want. Good size for my dog. Comes with a felt ball which is just stupid for fetch--gets so dirty. I like the color, my dog can see blue and she loves when I bring it out. I broke my first one, snapped the neck, but these work great, fine price. The amount of joy my dog gets from it is worth every penny.

Function is great, a bit breakable
Style: Classic, Size: 26in
This is probably the 3rd or 4th of this we've bought which reflects pros and cons--it is a great thrower, easy to use and great for keeping your hands clean with a dog who loves to play fetch! The con is that they're a bit brittle. We've broken a couple just smacking the plastic against a sidewalk, so you just have to be a little careful. Our puppy chewed on another one and destroyed it, so you might want to keep it out of the reach of your dogs when you're not using it!

Best toy EVER for a very active dog!
Style: Classic, Size: 26in
This is the best item I've purchased for my young Mini Schnauzer. He absolutely loves that I can now pitch the tennis ball quite a ways and he gets loads of running time. He begs for me to use this toy for him . . . he LOVES it! Easy on the arm as well!

Our dogs love it
Style: Classic, Size: 26in
On one of our trips to the dog park we saw someone using one of these with their dogs, it looked pretty neat and the ball flew so much farther than by hand. It wasn't very long before our dog got caught up in the excitement and joined the pack running after the tennis ball. Our dog stood with the rest of the dogs at the park staring at the ball in this launcher and waiting for the lady to throw it, once thrown the entire pack raced across the park after the ball,...they loved it! I decided to buy our own after watching and seeing how much fun they were having. This arrived a couple of days after I ordered it, and what struck me as funny was our dog recognized it as the toy from the dog park as soon as I pulled it out of the box. She couldn't wait to play. There is a small learning curve, but after a few trial throws I got the hang of it. This 26M launcher is a little large for me, it works but seems to work out better for my husband. I am going to order the smaller 18M size for myself. Both of our dogs had a great time, we had them running all over the place chasing after the ball. It was great being able to tire them out! With this launcher you can throw the ball farther and faster than you can by hand. Being able to scoop the ball up without having to touch it is a bonus, especially when the ball returns full of dirt and dog drool! This ball launcher can also be used with regular tennis balls too so if the ball that comes with the launcher gets lost it is easily replaced. Perfect toy for tiring out our dogs! *Update 9/24/16- I ordered the Junior 18M, it works so much better for me. The longer length of the 26M was starting to make my wrist sore, however my husband has had no issues. I'm 5'4" and my husband is 6'3" in case this info helps anyone make a decision on which one to buy. I know I went back and forth trying to figure out which one, which is why we now have two. ;)
