Looks like a bunch of fun to share with your dog – which begs the question, why not just throw the ball & leave out the device? Perhaps KaWoof would be useful if the dog owner has a shoulder injury, or some other disability, that makes throwing impractical. Or is the purpose of KaWoof to let the dog play fetch without a human present?
It would be interesting to see how long (or even if) a dog (or dogs) would continue to use KaWoof with no human present.
KaWoof is a Kickstarter project – funding ends in 27 days.

The government-led push to modernize its telecommunications system was unprecedented, experts say – & provides a cautionary tale for others who might like to try something similar.
“Australia was the first country where a totally national plan to cover every house or business was considered,” said Rod Tucker, a University of Melbourne professor & a member of the expert panel that advised on the effort. “The fact it was a government plan didn’t necessarily make it doomed. In Australia, we have changes of governments every three years, which really works against the ability to undertake long-term planning, & the long-term rollouts of networks like this.”
