When going into a store, get a cart from the parking lot, odds are in your favor that it will not have a stuck or wobbly wheel since other shoppers should have exchanged them inside the store. – Mike Brom
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.
