My husband is the canine Frisbee expert, he says it works great, our dog loves it!

We first got this for Steve when he could still see.. It remains one of the few toys he can still play with now that he is blind. This Frisbee and the LED balls are super fun and very high quality. The special batteries fit both products.. So you can buy a reasonable supply and they work for both. I wish there were more things that fell into this LEDcategory where night play is explored.. Anyway.. Another great product.

Apollo (Golden Lab) and I LOVE this Frisbe and the Collar. Got the Collar first, we like to walk at night and almost got run over one night by a guy on a bicycle in my sub (no lights). So got the collar, wonderful. Being we are out at night and Apollo lives for Frisbe, saw it online and decided to get it. It is the best, never has come apart where the battery is. Wish it was a little softer plastic. I have a gel frisbe also that doesn't light that we like for daytime. I would definately recommend this to everyone. People/neighbors think we are crazy this glowing red thing flying thru the air then running across the yard...LOL
