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

Great Idea but they will let you down eventually
I have used these for years during the winter. The price has nearly tripled but the longevity is the same. I normally purchase three with one being a spare. Within a few weeks they start going. I switch batteries etc but normally that does not help. Its a great idea and my dogs love them but they dont hold up to 10 minutes of play each nite. We do not throw them either, I roll them or kick them as my dogs are older
