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!
