Question: Is the disc soft? I want to get this for my dog but hard discs rip up her mouth.
Document: Amazingly, this disc flies almost as well as a regulation Ultimate disc. The light doesn't get in the way of the catch and it's proven to be durable. Scratching my head to pull out a negative and all I can come up with is that it's boring-looking in the daytime :)
This item is innovative (only one other similar product on the market, Black Jax, and I'm pretty sure this was out first) and cool and I really, really like it - don't get me wrong. The problem is that it is not water-resistant nor that great at floating, as described on Nite-Ize's own website: [...]We played with it for about an hour, maybe 90 minutes, in the water.
Water (and, therefore, a small amount of sand suspended in it) got into the part that twists to turn the light on, and the lights went out. No amount of careful cleaning and drying could bring it back to life fully--it flickered a bit, but it didn't last more than a second or two.
These look promising because rather than twisting-on, they have non-moving press-on type switches.
Answer: yes
