It is durable! Lights still working after a month of use
This is the first ball that my dog hasn’t been able to break the lights!

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!

Works Great!
This is a new version of an old style that was the best most durable, and long lasting night time balls!!! They stay on long enough for me to find if my lab cant find it. (We have an acre backyard and in ground swimming pool) sometimes I have to retrieve it. Stays on and auto shuts off after inactivity. They ARE waterproof and we play in the pool with them on night swims. My lab is very hard on balls, very few hold hold up to his chomping on them. Great balls!!

not worth the cost
I love these balls for night time ball playing but they dont last. The last 4 Ive bought havent worked well or lasted more than a month. They were once worth the money
