Our dogs love this ball launcher! I can throw the ball long distances without any arm strain. The balls wear out, and as described by others, tennis balls don’t fit. Buy extra balls if this is of concern. We bought a few of the “Chuck It” rubber 3” balls and they have worked well for our dogs. It’s a great value and fun for the dogs.

Chuckit!! Just Chuck it!!

Style: Sport, Size: Large

Chuck it further than your skinny little arms can chuck it. Doggo loved this, I loved this and when we were done Doggo promptly hid it under the porch so I couldn’t take it from him. It’s not a squeaky toy, it’s for fetch. You wing it out toward the yard and it flies, bounces if it’s lucky then is attacked in an adoring manner. We like it!!

Great For Dog Park Fun -- The Ball Goes Flying

Size: 25in, Style: Sport

I love this thing. It's super well made and It enables me to chuck a ball the entire length of the dog park (I'm a 65 yr old woman with a wimpy arm). My dog is thrilled too. At first I thought it might be too heavy, but that's just not an issue, the weight is fine. For non-throwers like me someone at the dog park gave me a tip --- just look at the area you want to throw the ball. Helped my aim immensely. The 2.5 inch chuck it ball it comes with is my dog's absolute *favorite* . . . it's her security blanket in the kennel while driving, and it's her favorite ball to chase (the only one she'll actually bring back). She loves to chew it and to squish the air out of it, which takes a little effort. Recommend.

Great tool!

Size: 18in, Style: Sport

Ok - so I do not have a dog!!! I purchased this item for a completely different purpose! I saw someone using this to gather eggs!! I often go to my daughter and son-in-law's homestead to carry out the chores when they need to be out of town! Well, I am a bit on the short side (4'11") and some of the hens KNOW that a short person is going to be gathering eggs!!! I simply could not reach all of the eggs in a couple of the nesting boxes! So, after seeing someone else use this ball launcher as an egg retriever, I bought one! I am now able to reach ALL of the eggs - one at a time with no breakage! It was a game changer for me. I am sure that it works equally well for dog play!!!
