I have been looking for the best snow chains for my tires in the winter. I am most interested in those with easy installation and quick removal under duress. Faffing about with complicated easily-tangled stuff is a singularly joyless experience.
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.
