A friend gave my dog this ball in January, and my dog and I like it so much that I have since started to phase-out other dog toys. It is durable. My dog is a strong chewer, and has destroyed many a lesser toy. It is attractive. Who doesn’t love a geodesic dome? It is light and squishy, bouncing off objects denser balls would damage. It is large. This might not seem important, but my dog has been known to attempt furniture disassembly while attempting to retrieve a ball that has rolled under the sofa. Despite its size, it is easy to pick up. Dogs can chomp on a vertex, and I can hook it with a finger. Touching it is not disgusting. Despite its size, it has little surface area to get slimy. And no tennis ball fuzz.
A cool tool is anything useful that is superior to comparable items. If you think this tool is inferior suggest a better one. You are welcome to insult a tool, but comments containing insults to individual people will be deleted. Corrections of fact are always welcomed, if stated politely. Recommendations of better tools are dearly wanted and may be elevated to the front page.
