Disappointed in this. I have the large size and expected a smaller version of the rubber ball. Instead this came with a ball covered in fabric. The dogs I bought it for won't play with the ball. Maybe it is my fault for not reading more closely but why would Chuck-It even sell something so cheap and poorly made. Dogs can easily rip the fabric off the rubber (which is in two pieces). Very strangely made. Now I have buy a ball to use it.

Launches!!!

Style: 14" Length Sport Launcher

Please note that this launcher is for a smaller sized chuckit - it came as a package deal with an order of small fuzzy chuckits and it works GREAT. Recommend using in dry weather since the water sprays when wet (or just be better at throwing than us!)

waste of money, useless

Style: 14" Length Sport Launcher

Tiny size and matching ball that it slings right in front of you. When it says small dogs it must mean the size of a rat. This is nearly useless. One star for durability since it's plastic.

Durable

Honestly I didn't think this ball would last but 2 years later and only one battery change later and it is going strong. This ball has given me so much more time to play with my dog since I can throw the ball at night on short winter days I can't recommend it enough. I can throw the ball at night and my dog can find it in the dark. Add a collar LED and it's a funny light show of one light intercepting another.

Great for pm at the park!

This is alot like Nite Eyez but not as good but if you have never used Nite Eyez you will love this!! I have an am. staff that i take to the park at night so she can run around without the fear of a dog running up on her (she doesn't like that) and this ball is great! Stays lit and changes colors and it she cant destroy it!
