I’ve been using this automatic dog ball launcher since the day I received it, and it has honestly been amazing for both me and my dog. My pup took to it surprisingly fast, and now he plays with it every day without getting bored. I love the adjustable distance settings because I can use it indoors or outdoors depending on the weather. The toy is a very good size and quite practical. In the days I’ve been using it, the product's quality has really stood out, as it has proven to be highly effective. I believe it offers excellent value for the quality, and I recommend it if you are looking to keep your pet entertained.

Do Not Use The Balls That Come With It!

Color: White

This ball machine shows 6 meters or 19 feet. Unlike other ball launchers this is too powerful for indoor use. But I found that if you use different balls through experimentation then there are some that do not go as far.

100 de 100 fabuloso

Color: White, Color: White

The best gift for my dog! I absolutely loved the design and its features—I can adjust the ball-launching distance, and the fact that it’s rechargeable is fantastic. The material of the balls is durable, too. My dog’s name is Oreo; I set up his toy in the yard, and it was so much fun watching him play outdoors. I’m currently teaching him how his new toy works. I highly recommend this for our four-legged babies—5 stars!
